The installer now checks that port 8080 is available and not in use by
any other application.
The port checker has been rewritten to use bind() rather than just
checking if a server responds on localhost. It's much more reliable and
detects more problems.

In case of an error, ipapython.ipautil.run() now raises an exception that
contains the error message of the failed command. Before the exception
only contained the command and error code.
The command is no longer collapsed into one string. The error message
and logging output contains the actual command and arguments with intact
quoting.
Example:
CalledProcessError(Command ['/usr/bin/python3', '-c', 'import sys; sys.exit(" ".join(("error", "XXXXXXXX")))'] returned non-zero exit status 1: 'error XXXXXXXX\n')

Previously bf9886a84393d1d1546db7e49b102e08a16a83e7 match_local has
undesirable side effect that CheckedIPAddress object has set self._net
from local interface.
However with the recent changes, match_local is usually set to False,
thus this side effect stops happening and default mask per address class
is used. This causes validation error because mask on interface and mask
used for provided IP addresses differ (reporducible only with classless
masks).
FreeIPA should compare only IP addresses with local addresses without masks

Previously, a separate thread would be created for each socket used
for conncheck. It would also time out after one second, after which it
would be closed and reopened again. This caused random failures of
conncheck.
Now all sockets are handled in a single thread and once the server
starts to listen on a port, it does not close that connection until the
script finishes.
Only IPv6 socket is used for simplicity, since it can handle both IPv6
and IPv4 connections. This requires IPv6 kernel support, which is
required by other parts of IPA anyway.

pylint is having a hard time with distutils.version in tox's virtual
envs. virtualenv uses some tricks to provide a virtual distutils
package, pylint can't cope with.
https://github.com/PyCQA/pylint/issues/73 suggests to use pkg_resources
instead. pkg_resources' version parser has some more benefits, e.g. PEP
440 conformity. But pkg_resources.parse_version() is a heavy weight solution
with reduced functionality, e.g. no access to major version.
For API_VERSION and plugin version we can use a much simpler and faster
