Add GnuPG encryption support for addresses with delimiters
...
If a user registers their key for address alice@example.com but receives a
message sent to alice+something@example.com , this message should be encrypted
as well.
- Implement delimiter support for GnuPG encryption.
- Add E2E test case for a clear text message delivered to an address with
delimiter.
- Fix minor bug: wrong configuration parameter was retrieved when logging
information about enc_domain_keymap being active.

Record execution time and log it
...
After each execution, log an entry with information about total seconds from
the start to the end of execution and the value returned by
time.process_time() function, which returns:
sum of the kernel and user-space CPU time
according to the documentation.
This feature can be used to collect stats about Lacre performance.

- Replace custom logging code with calls to logging module.

To make Lacre's logging more flexible, use fileConfig from logging.config to
set up all parameters. If the configuration file is missing, use dictConfig
with hardcoded reasonable defaults.

Making GPG-Mailgate compatible with RFC 2821 (Simple Mail Transfer Protocol). The previous reverted commits made the gateway incompatible with the RFC. However, compatibility has to be activated in the settings. Most mail servers ignore the case sensitivity of the mail addresses, so this should not be a big issue.
...
A quick solution to make the S/MIME functionality compatible with the RFC was not found so this needs to be fixed later.
