[joaopinto14]

New Functionality

Add the ability to define the number of connections and the lifetime of database connections.

Error

[eu.kennytv.maintenance.lib.hikari.pool.PoolBase]: HikariPool-1 - Failed to validate connection eu.kennytv.maintenance.lib.mysql.cj.jdbc.ConnectionImpl@63b14429 (No operations allowed after connection closed.). Possibly consider using a shorter maxLifetime value.

The mysql has been replaced with a redis connection instead now
