Since it is not really possible to separate SSH errors from
errors of the called program, add a SSH check before
calling replica-conncheck on the master.
The check also adds the master to a temporary known_hosts file,
so suppressing SSH's warning about unknown host is no longer
necessary. If the "real" connection fails despite the check,
any SSH errors will be included in the output.

New servers that are installed with dogtag 10 instances will use
a single database instance for dogtag and IPA, albeit with different
suffixes. Dogtag will communicate with the instance through a
database user with permissions to modify the dogtag suffix only.
This user will authenticate using client auth using the subsystem cert
for the instance.
This patch includes changes to allow the creation of masters and clones
with single ds instances.
Many functions use low-level socket interface for connection or
various checks. However, most of the time we don't respect
automatic address family detection but rather try to force our
values. This may cause either redundat connection tries when an
address family is disabled on system tries or even crashes
when socket exceptions are not properly caught.
Instead of forcing address families to socket, rather use
getaddrinfo interface to automatically retrieve a list of all
relevant address families and other connection settings when
connecting to remote/local machine or binding to a local port.
Now, we will also fill correctly all connection parameters like
flowinfo and scopeid for IPv6 connections which will for example
prevent issues with scoped IPv6 addresses.
bind_port_responder function was changed to at first try to bind
to IPv6 wildcard address before IPv4 as IPv6 socket is able to
accept both IPv4 and IPv6 connections (unlike IPv4 socket).
nsslib connection was refactored to use nss.io.AddrInfo class to
get all the available connections. Socket is now not created by
default in NSSConnection class initializer, but rather when the
actual connection is being made, becase we do not an address family
where connection is successful.

UDP port checks in ipa-replica-conncheck are too strict. The entire
conncheck fails when UDP ports cannot be verified as open. However,
UDP protocol is unrealiable by its nature and the port can also not
be checked if there is an application already bound to it. This can
happen for example when ipa-replica-conncheck is run as a part of
ipa-ca-install and the replica services are thus already running.
This patch changes the behavior of UDP port checks. The conncheck
script now rather reports a warning that UDP port cannot be verified
but does not fail the entire test.

UDP port checks in ipa-replica-conncheck always returns OK even
if they are closed by a firewall. They cannot be reliably checked
in the same way as TCP ports as there is no session management as
in TCP protocol. We cannot guarantee a response on the checked
side without our own echo server bound to checked port.
This patch removes UDP port checks in replica->master direction
as we would have to implement (kerberos) protocol-wise check
to make the other side actually respond. A list of skipped
ports is printed for user.
Direction master->replica was fixed and now it is able to report
error when the port is blocked.

A server may have 2 or more NICs and its hostname may thus resolve
to 2 and more forward addresses. IP address checks in install
scripts does not expect this setup and may fail or crash.
This script adds a support for multiple forward addresses for
a hostname. The install scripts do not crash now. When one IP
address is needed, user is asked to choose from all detected
server IP addresses.
https://fedorahosted.org/freeipa/ticket/2154
It is pointless to report failures for all checked ports when the
target hostname is not resolvable - user may get easily confused.
This patch changes this behavior so that conncheck fails with
a proper error and does not even continue to port probing part.

change default_logger_level to debug in configure_standard_logging
add new ipa_log_manager module, move log_mgr there, also export
root_logger from log_mgr.
change all log_manager imports to ipa_log_manager and change
log_manager.root_logger to root_logger.
add missing import for parse_log_level()
When getpass.getpass() function is interrupted via CTRL+D, EOFError
exception is thrown. Most of the install tools are not prepared for
this event and crash with this exception. Make sure that it is
handled properly and nice error message is printed.

If we can get a ticket for the master then we know we got all right.
This should avoid being prompted again by ssh if the kinit failed and for some
reason the error was not caught (seen in live tests).
We need to check all Kerberos ports both TCP and UDP transports.
Since we have the PKI proxy configuration all communication with the CA happens
on the standard 80/443 ports so we need to check them always.
We do not need to leave the old CA ports open. These ports are still used
locally but not over the network.
When IPA replica is installed and the master machine record is not
in ~/.ssh/known_hosts, ipa-replica-install will prompt user to answer
a question about adding a host to this file.
This has, however, a potential to break automatic tests.
ipa-replica-conncheck should not require any further user interaction
when all mandatory options are filled.

When connection between a master machine and future replica is not
sane, the replica installation may fail unexpectedly with
inconvenient error messages. One common problem is misconfigured
firewall.
This patch adds a program ipa-replica-conncheck which tests the
connection using the following procedure:
1) Execute the on-replica check testing the connection to master
2) Open required ports on local machine
3) Ask user to run the on-master part of the check OR run it
automatically:
a) kinit to master as default admin user with given password
b) run the on-master part using ssh
4) When master part is executed, it checks connection back to
the replica and prints the check result
This program is run by ipa-replica-install as mandatory part. It
can, however, be skipped using --skip-conncheck option.
ipa-replica-install now requires password for admin user to run
the command on remote master.
