(PUP-1811) Set regexp match vars on regexp match using in operator
(PUP-1811) Add tests for regexp search in array setting match vars
(PUP-2654) Capitalize each segment of a resource type "label"

When a Resource type is stringified it selects the short notation
(e.g. Fee::Foo) over the longer (e.g. Resource[Fee::Foo]), and
when doing so it should output each segment of the FQN with a
capital letter. The current implementation only capitalizes
the initial letter (e.g. Fee::foo::fum).

This fixes the implementation of
TypeCalculator.string_PResourceExpression to capitalize all segments.
Merge pull request #2789 from hlindberg/PUP-1811_in-set-match-vars

(PUP-1811) Make 'in' set match vars when regexp is used to match
(maint) Extract constant for name separator

The name separator is used a few different times in the file. This
extracts it out and freezes the value, which has the nice benefit of a
small speed boost. Unfortunately this isn't a big win for the system
since this code path is only really used for error conditions.
(doc) Describe ca subcommands in puppet help

PUP-2801 requests ability to remove pending CSRs. The requester confirmed
that the puppet ca destroy command met that need. This patch adds basic
descriptions to puppet help ca for destroy, revoke, generate, sign,
print, fingerprint, and verify. The descriptions are largely sourced from
the puppet help cert descriptions of the same functionality.
