(#19201) Add concat function to join two arrays

Without this patch applied there is no easy way to append one array to
another.  This is a problem because it is often desirable to join two
arrays without flattening the contents into a single, one dimensional
array.

This patch addresses the problem by adding a `concat()` function which
takes two arguments.  The arguments will be concatenated together and a
new array returned to the caller.

(#19272) Add has_element() function

It is exceptionally difficult to determine if an array contains an element matching a specific value without an iteration or loop construct.

This function is the Puppet equivalent of Array.includes?(foo) in Ruby.  The implementation is a verbatim copy of has_key() with the minor modifications needed to support arrays instead of hashes.

(#19272) Add has_element() function
Revert "Merge pull request #130 from jhoblitt/has_element"

This reverts commit f7a18189ec338b01b0fc89d75def832753af3868, reversing
changes made to 36a7b29630a4d4de17af79b5dd4e9491ec20b123.

I'm reverting this change because of concerns raised by Peter Meier that
it duplicates the "in" operator in the DSL.  The "in" operator is new
information that I did not posses when I made the decision to merge.
Because of this new information I'm un-merging and continuing the
discussion in the comments of
https://projects.puppetlabs.com/issues/19272

(maint) Add Ruby 2.0.0 to Travis build matrix

Without this patch we're not testing against Ruby 2.0.0 which has recently been
released.  This is a problem because we'd like a way to be notified if a change
set breaks compatibility with future supported versions of Ruby.

This patch should not be taken as an indication that we fully support Ruby 2.0,
just as an indication that we plan to in the future.

This patch also tightens up the specifications of the build matrix.  In
addition to testing against the specific Puppet dependency versions, we're also
testing against the latest 2.7.x release and the latest release.
