Describe the changes you're proposing

Details are in the issue attached but my change iterates through an array of parameters and writes the parameters on indivitual lines rather than dumping an array into the configuration file. The array dump is not parsable by mysql and it causes issues.

Pillar / config required to test the proposed changes

Example

mysql:
  server_config:
    file: 50-server.cnf
    # my.cnf sections changes
    sections:
      mysqld:
        replicate-ignore-table:
          - core.table1
          - core.table2                 
          - core.table3   

currently gets interpreted as

replicate-ignore-table = ['core.table1', 'core.table2', 'core.table3']
rather than the correct

replicate-ignore-table                  = 'core.table1'
replicate-ignore-table                  = 'core.table2'
replicate-ignore-table                  = 'core.table3'

This works on any array config value.
