MAR-28: Implemented additional tests for mail_server role:
- Deploy a number of tools on clients in order to test SMTP, IMAP, and Sieve
services.
- Added one more user to LDAP directory for testing group restrictions.
- Deploy CA certificate on all testing machines for TLS validation purposes.
- Use different custom-configured cipher for mail server ciphers.
- Fixed invalid postmaster address for parameters-optional host.
- Deploy configuration files for use with Imap-CLI on client test machines.
- Updated testing of SMTP server to include checks for users that do not belong
to mail group.
- Extended some SMTP-related tests to cover both test servers.
- Some small fixes in SMTP-related tests for expected output from commands.
- Implemented tests covering Dovecot (IMAP + Sieve) functionality.
- Implemented tests for running/enabled services.
- Implemented tests for ClamAV.
- Implemented tests for firewall and connectivity.
- Implemented tests for Postfix TLS configuration.
- TODO: Tests for Sieve TLS configuration have not been written yet due to
limitation of available tools.
