- Created nodepool::mysql class, which includes mysql stuff from init.pp. This allows to host database on separated host than the one running nodepool. - Discarded creation of 'max_connections.cnf' file. Instead, use 'max_connections' from '::mysql::server' config_hash/override_options. Change-Id: Ic745875b69563ed3834e99533227ca3d1150156b
