3.1.0

• New parameter pool_purge for php::extension to remove files not
  managed by puppet from the pool directory.
• The pecl_source parameter for php::extension was renamend to
  source because it is also useful for PEAR extensions.
  pecl_source can still be used but is deprecated and will be
  removed in the next major release.
• Parameters referring to time in php::fpm::config can now be
  specified with units (i.e. '60s', '1d'):
  • emergency_restart_threshold
  • emergency_restart_interval
  • process_control_timeout
• The PEAR version is not independant of $php::ensure and can be
  configured with $php::pear_ensure
• Give special thanks to the contributors of this release:
  • Petr Sedlacek
  • Sherlan Moriah
