Petr Viktorin 7336a176b4 Add the version option to all Commands
Several Commands were missing the 'version' option. Add it to those
that were missing it.

Do not remove the version option before calling commands. This means
methods such as execute(), forward(), run() receive it.
Several of these needed `**options` added to their signatures.
Commands in the Cert plugin passed any unknown options to the underlying
functions, these are changed to pass what's needed explicitly.
Some commands in DNS and Batch plugins now pass version to commands
they call.

When the option is not given, fill it in automatically. (In a subsequent
commit, a warning will be added in this case).

Note that the public API did not change: all RPC calls already accepted
a version option. There's no need for an API version bump (even though
API.txt changes substantially).

Ping the remote IPA server to ensure it is running.
The ping command sends an echo request to an IPA server. The server
returns its version information. This is used by an IPA client
to confirm that the server is available and accepting requests.
The server from xmlrpc_uri in /etc/ipa/default.conf is contacted first.
If it does not respond then the client will contact any servers defined
by ldap SRV records in DNS.
EXAMPLES:
Ping an IPA server:
ipa ping
------------------------------------------
IPA server version 2.1.9. API version 2.20
------------------------------------------
Ping an IPA server verbosely:
ipa -v ping
ipa: INFO: trying https://ipa.example.com/ipa/xml
ipa: INFO: Forwarding 'ping' to server u'https://ipa.example.com/ipa/xml'
-----------------------------------------------------
IPA server version 2.1.9. API version 2.20
-----------------------------------------------------

A possible enhancement would be to take an argument and echo it
