Issue with non -alphanumeric Postgresql configuration value

[walbertus]

The Patroni cannot start when it use non-alphanumeric value for value in patroni_postgresql_parameters and patroni_bootstrap_dcs_postgresql_parameters.

e.g:

patroni_postgresql_parameters:
  - { option: "listen_addresses", value: "*" }
  - { option: "log_line_prefix", value: "%t [%p]: [%l-1] user=%u,db=%d,client=%h" }
