1511: Setup, compose: add note about reverse DNS r=mergify[bot] a=liquidat
## What type of PR?
documentation
## What does this PR do?
If the [mailu setup utility](https://setup.mailu.io/master/) is used with the Compose flavor, in step 4 a list of public host names needs to be provided:
The [first entry in this list is configured as hostname by postfix](ddac2672fc/core/postfix/conf/main.cf (L10)). That is crucial: if the reverse DNS entry for that host is not the same as this first entry in this list, it will be a mismatch between rDNS and HELO, which will lead to bad scoring in many spam filters.
This commit clarifies that point.
It also fixes a missing parenthesis.

Rate limiting was already redesigned to use Python limits. This
introduced some unexpected behavior, including the fact that only
one criteria is supported per limiter. Docs and setup utility are
updated with this in mind.
Also, the code was made more generic, so limiters can be delivered
for something else than authentication. Authentication-specific
code was moved directly to the authentication routine.
886: Ipv6 support r=mergify[bot] a=muhlemmer
## What type of PR?
(Feature, enhancement, bug-fix, documentation) -> A bit of everything
## What does this PR do?
Document how to use ipv6nat. This, however triggers some kind of flaky behavior with the Docker DNS resolver, resulting in lookup failures between containers. So all resolving needs to be done during container startup/configuration.
In order not to pollute every single start.py file, we've created a small library called [Mailu/MailuStart](https://github.com/Mailu/MailuStart). As an addition, this library also defines the template generation function, including its logging facility.
Note: `docker-compose.yml` downgrade is necessary, as IPv6 settings are not supported by the Docker Compose file format 3 😞
### Related issue(s)
Supersedes PR #844
- Fixes#827
- Hopefully helps with #829 and #834
## No backport yet
This PR directly imports MailuStart from git. This makes it a bit more simple to implement on the short term an do some testing and probably some future improvements. When everything is proved stable, we will create a proper PyPi package with versioning and consider back porting.

This will make network configuration and host based authentication
more robust, across different deployment platforms.
The options `RELAYNETS` and`POD_ADDRESS_RANGE` are kept for compatibility.
However, their usage have become optional.
