When configuring the 389 Directory Server instance, we tune it
so that number of file descriptors available to the DS is increased
from the default 1024 to 8192.

There are platform specific steps that need to be conducted
differently on systemd compatible platforms and sysV compatible
platforms.

systemd: set LimitNOFILE to 8192 in /etc/sysconfig/dirsrv.systemd
sysV: set ulimit -n 8192 in /etc/sysconfig/dirsrv
      set ulimit - nofile 8192 in /etc/security/limits.conf

Differences in the python byte code fails in a build validation
(rpmdiff) done on difference architecture of the same package.

This patch:
 1) Ensures that timestamps of generated *.pyo and *.pyc files match
 2) Python integer literals greater or equal 2^32 and lower than 2^64
    are converted to long right away to prevent different type of
    the integer on architectures with different size of int

Using the --ignore-dependencies switch was causing the ipactl stop command
not to stop all instances of dirsrv and dogtag. Make sure the switch is used
only when necessary, i.e. to prevent ipa-otpd.socket from getting stuck during
the shutdown transaction.

Make sure ipactl status check for correct DS instance. It should check for
'dirsrv@IPA-REALM' and not 'dirsrv.target'.

The plugin hooks into the Nose runner and IPA's logging infrastructure
and calls the appropriate BeakerLib functions (rl*).
