2646: Smarter ratelimit r=mergify[bot] a=nextgens
## What type of PR?
enhancement
## What does this PR do?
Only account for **distinct** usernames in the IP rate-limiter.
This enables to have a much tighter default as a user with a misconfigured device will now only account for a single attempt.
The goal here is to make the rate-limiter more acceptable and to avoid people disabling it altogether.

2631: Restful api finishing touches r=mergify[bot] a=Diman0
## What type of PR?
enhancement
## What does this PR do?
Some finishing touches for the restful api.
- Make the API configurable via the setup utility.
- Configured exactly the same as the ADMIN and WEBMAIL.
- We have a single config (API) that configures whether it is exposed (via front). Just like ADMIN. The API is always reachable by directly connecting to the admin container.
- API_TOKEN does not enable/disable the API anymore. When it is not configured, an error is returned (via the internet browser) that the API_TOKEN must be configured in mailu.env.
- Fix some small bugs in the setup utility ( selecting none in the dropdown boxes, now correctly changes the config)
- Update Flask-RestX to 1.0.5. This resolves the deprecation warnings introduced by Flask-RestX.

2613: Enhance network segregation r=nextgens a=nextgens
## What type of PR?
enhancement
## What does this PR do?
- put radicale and webmail on their own network: this is done for security: that way they have no privileged access anywhere (no access to redis, no access to XCLIENT, ...)
- remove the EXPOSE statements from the dockerfiles. These ports are for internal comms and are not meant to be exposed in any way to the outside world.

2464: Introduce RESTful API r=mergify[bot] a=Diman0
## What type of PR?
Feature
## What does this PR do?
Introduces a RESTful API for changing the complete Mailu config.
Anything that can be configured in the web administration interface, can also be configured via the Mailu RESTful API.
Via the swagger.json endpoint the complete OpenAPI specification can be retrieved.
Via the endpoint swaggerui, a web client is available which shows all the endpoints, data models and allows you to submit requests.
See docs/api.rst and docs/configuration.rst for details for enabling it.

2603: Enable HAPROXY protocol on SUBNET r=mergify[bot] a=nextgens
## What type of PR?
bug-fix
## What does this PR do?
- Enable HAPROXY in between front and imap: With this we avoid running into the limitations of ``mail_max_userip_connections`` and the logfiles reflect the real IP.
- Enable HAPROXY in between front and smtp: with this postfix and rspamd are aware of whether TLS was used or not on the last hop. In practice this won't work as nginx doesn't send PROTO yet.
- Discard redundant log messages from postfix
With all of this, not only are the logs easier to understand but ``doveadm who`` also works as one would expect.

2596: db.String without length cause an error in migration for MySQL DB r=mergify[bot] a=csthiang
## What type of PR?
bug-fix
## What does this PR do?
For MySQL, `db.String` requires a length because db.String gets translated to `VARCHAR` in MySQL and `VARCHAR` requires a length. I was considering adding a length to it but since the affected fields were used to store CommaSeparatedList and json-encoded string, I have a feeling it can be quite large in the future. `db.Text` seems to fit into this use case but please correct me if I am wrong.
This actually affects a DB migration with the following error:

This is not perfect...
- dovecot now complains about waitpid/finding a new process
- postfix is still regularly pinging rspamd / his milter and that
generates a few lines worth of logs each time.
With this we avoid running into the limitations of
mail_max_userip_connections (see #894 amd #1364) and the
logfiles as well as ``doveadm who`` give an accurate picture.
Anything that can be configured in the web administration interface,
can also be configured via the Mailu RESTful API.
See the section Advanced configuration in the configuration reference
for the relevant settings in mailu.env for enabling the API.
(API, WEB_API, API_TOKEN).

Feature
## What does this PR do?
