This PS simplifys the db start and init script, increasing robustness of the mariadb chart on low end hardware. It also removes some unrequired annotations and moves to more explicit qualification of the clustering variables. Change-Id: I6cff5fb6ccfdcc6c82203b0e5eff445ee98bc298

## Generally, it is unwise to set the query cache to be larger than 64-128M
|

## as the costs associated with maintaining the cache outweigh the performance
|
|
## gains.
|
|
## The query cache is a well known bottleneck that can be seen even when
|
|
## concurrency is moderate. The best option is to disable it from day 1
|
|
## by setting query_cache_size=0 (now the default on MySQL 5.6)
|
|
## and to use other ways to speed up read queries: good indexing, adding
|
|
## replicas to spread the read load or using an external cache.
