"""

Nagios Plugin to check the number of deployed Blue Talon policy endpoints via the Policy Management server REST API

Optional thresholds may be applied against the number of PEPs, defaulting to a lower boundary (can also use
the min:max threshold format) to check we have the expected number of PEPs, for use in a stable environment when
things shouldn't be changing that much.
