This work converts all the tests over to beaker. Some things are
done slightly different in beaker, we rely much more heavily on
catch_failures rather than explicitly laying out the exit codes we
want but I have attempted to preserve the spirit of all tests.
This patch is a fix for the race condition that keeps occuring during
postgresql setup. Its very rare on its own, but when you are using this
module in a CI environment it happens quite frequently.
Basically what happens is that sometimes the service will announce the
database has started, but really it is still working in the background.
Sometimes the unix socket may not be listening, and sometimes the
system is still loading and you get a weird client error.
The fix itself is a modification to postgresql::validate_db_connection
so that it is able to connect on the local unix socket, plus retry
until the database is available.
This new and improved validate_db_connection can then be put into the
build pipeline (in the service class in particular) to ensure the
database is started before continuing on with the remaining steps.
This in effect blocks the puppet module from continuing until the
postgresql database is fully started and able to receive connections
which is perfect.
Tests and documentation provided.

This is a very very large change to the module. It started out as a fix to add
postgresl::server::config_entry, and quickly became a rewrite to fix a lot of
ordering issues inherent in the API.
Since this changes the Public API it is considered a backwards compatible
change.
See the upgrading guide in README.md for more details as to what has been
modified in this patch.
