mariadb: Move generation of systemd drop-in to puppet-tripleo
Systemd starts mariadb as user mysql, so in order to allow a large number of connections (e.g. max_connections=4096) it is necessary to raise the file descriptor limit via a system drop-in file. When installing an undercloud, such drop-in file is currently generated by instack-undercloud (in file puppet-stack-config.pp). But non-HA overcloud also need such drop-in to be generated. In order to avoid duplicating code, the drop-in creation code should be provided by puppet-tripleo. By default, no drop-in is generated; it has to be enabled by instack-undercloud or tripleo-heat-template once they will use it (resp. to create undercloud or non-HA overcloud). This patch does not aim at generating a dynamic file limit based on the number of connections, this should land in another dedicated patch. Instead, it just reuses the limit currently set for undercloud and HA-overclouds. Also, the generation of the drop-in does not force a mysql restart like it currently does in instack-undercloud, to avoid unexpected service disruption on a non-HA overcloud after a minor update.
