9.5 pg_controldata output not compatible with PAF

[mrimbault]

In 9.5 version of PostgreSQL, the output of pg_controldata changed.
PAF RA expects wal_level related line to start with "Current wal_level setting:", but it now start with "wal_level setting:".

This breaks the agent, that fails immediately with a "OCF_ERR_INSTALLED" return code, bringing the resource down.

The problem occurs at this line: https://github.com/dalibo/PAF/blob/master/script/pgsqlms#L856

This check needs to be adapted.
