(PDB-847) fix PE compatibility bug

This patch deletes the GlobalCheck method that ran before each call to
the PDB indirectors to check that the running version of Puppet was greater
than 3.5. The check is redundant because Puppet 3.5 is a requirement for
puppetdb-terminus and was causing a bug by mis-parsing PE semvers.

(PDB-707) Fix bonecp 57P01 handling

This patch adds retry handling for 57P01 failures, which result in an
PSQLException with a status code of 08003. The patch has been made
forward compatible by catching all SQLExceptions with this status code.

Version 0.8.0-RELEASE of Bonecp does not throw the correct sql state code
today, however a patch has been raised to make this happen so we can
upgrade to this version in the future.
