Allow for certificate-based authentication from Patroni PostgreSQL accounts (#1134)

Browse Source 
The two principal features this introduces:

1. Provide the Patroni PostgreSQL management accounts (superuser, replication, rewind) to be able to authenticate using certificate-based authentication
2. Allow the user to specify the `sslmode` they wish to connect as.

- **superuser**:
- **username**: name for the superuser, set during initialization (initdb) and later used by Patroni to connect to the postgres.
- **password**: password for the superuser, set during initialization (initdb).
- **sslmode**: (optional) maps to the `sslmode <https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNECT-SSLMODE>`__ connection parameter, which allows a client to specify the type of TLS negotiation mode with the server. For more information on how each mode works, please visit the `PostgreSQL documentation <https://www.postgresql.org/docs/current/libpq-ssl.html#LIBPQ-SSL-SSLMODE-STATEMENTS>`__. The default mode is ``prefer``.
- **sslkey**: (optional) maps to the `sslkey <https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNECT-SSLKEY>`__ connection parameter, which specifies the location of the secret key used with the client's certificate.
- **sslcert**: (optional) maps to the `sslcert <https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNECT-SSLCERT>`__ connection parameter, which specifies the location of the client certificate.
- **sslrootcert**: (optional) maps to the `sslrootcert <https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNECT-SSLROOTCERT>`__ connection parameter, which specifies the location of a file containing one ore more certificate authorities (CA) certificates that the client will use to verify a server's certificate.

- **username**: replication username; the user will be created during initialization. Replicas will use this user to access master via streaming replication

- **password**: password for the user for ``pg_rewind``; the user will be created during initialization.

- **on\_restart**: run this script when the postgres restarts (without changing role).
- **on\_role\_change**: run this script when the postgres is being promoted or demoted.
