Subject: Ticket 48771 - lib389 - get ns-slapd version


Bug description:
Some tests should be executed only with 389-ds-base
that implements required features/has fixes. This can be done with
py.test skipif fixture. But we don't have a way to get the version
of ns-slapd that is currently used.

Fix description:
Add functions get_ds_version() and ds_is_older().
get_ds_version() returns a string like "1.3.4.8 B2016.043.2254"
ds_is_older(version) returns boolean value if the current version is
older than provided string.
