2058: Implement versioning for CI/CD workflow. r=mergify[bot] a=Diman0

## What type of PR?

Feature!

## What does this PR do?
This PR introduces 3 things
- Add versioning (tagging) for branch x.y (1.8). E.g. 1.8.0, 1.8.1 etc.
  - docker repo will contain x.y (latest) and x.y.z (pinned version) images.
  - The X.Y.Z tag is incremented automatically. E.g. if 1.8.0 already exists, then the next merge on 1.8 will result in the new tag 1.8.1 being used.
- Make the version available in the image.
  -  For X.Y and X.Y.Z write the version (X.Y.Z) into /version on the image and add a label with version=X.Y.Z
	  -  This means that the latest X.Y image shows the pinned version (X.Y.Z e.g. 1.8.1) it was based on. Via the tag X.Y.Z you can see the commit hash that triggered the built.
  -  For master write the commit hash into /version on the image and add a label with version={commit hash}
-  Automatic releases. For x.y triggered builts (e.g. merge on 1.9) do a new github release for the pinned x.y.z (e.g. 1.9.2). 
  -  Release shows a static message (see RELEASE_TEMPLATE.md) that explains how to reach the newsfragments folder and change the branch to the tag (x.y.z) mentioned in the release. Now you can get the changelog by reading all newsfragment files in this folder.

This PR does not change anything to our workflow (what we (human persons) do). Our processes are still exactly the same. The above introduced logic is automatic. When we backport to X.Y all the magic for creating the pinned version X.Y.Z is handled by the CI/CD workflow.

## Testing
Suggested testing steps. This should cover all situations including BORS. It does require that you use your own docker repo or temporarily create a new one.
Suggested testing steps.
1. Create new github repo.
2. Add the required docker secrets to the project (see beginning of CI.yml for the secret names), DOCKER_UN, DOCKER_PW, DOCKER_ORG, DOCKER_ORG_TESTS.
3. Clone the project.
4. Copy the contents of the PR to the cloned project.
5. Push to your new github repo.
6. Now master images are built. Check that images with tag master are pushed to your docker repo
7. Check with docker inspect nginx:master that it has the label version={commit hash}.
8. Run an image, run `docker-compose exec <name> cat /version`. Note that /version also contains the pinned version. For master the pinned version is the commit hash.
9. Create branch 1.8. 
10. Push branch 1.8 to repo.
11. Note that tags 1.8 and 1.8.0 are built and pushed to docker repo
12. Inspect label and /version. Note that 1.8 and 1.8.0 both show version 1.8.0.
13. Push another commit to branch 1.8.
14. Note that tags 1.8 and 1.8.1 are built and pushed to docker repo
15. Inspect label and /version. Note that 1.8 and 1.8.1 both show version 1.8.1.
16. Let's check BORS stuff.
17. Create branch testing.
18. Push the commit with the exact commit text (IMPORTANT!!): `Try #1234:`'.
19. Note that images are built and pushed for tag `pr-1234`.
20. Inspect label and /version. Note that the version is `pr-1234`.
20. Create branch staging.
21. Push the commit with commit text: `Merge #1234`.
22. Note that this image is not pushed to docker (as expected).

## What type of PR?

Feature: it implements a credential cache to speedup authentication requests.

## What does this PR do?

Credentials are stored in cold-storage using a slow, salted/iterated hash function to prevent offline bruteforce attacks. This creates a performance bottleneck for no valid reason (see the
rationale/long version on https://github.com/Mailu/Mailu/issues/1194#issuecomment-762115549).

1776: optimize generation of transport nexthop r=mergify[bot] a=ghostwheel42

## What type of PR?

bug-fix and enhancement.

## What does this PR do?

Possibly there should be more input validation when editing a relay, but for now this tries to make the best out of the existing "smtp" attribute while maintaining backwards compatibility. When relay is empty, the transport's nexthop is the MX of the relayed domain to fix  

```
RELAY			NEXTHOP						TRANSPORT
empty			use MX of relay domain				smtp:domain
:port			use MX of relay domain and use port	smtp:domain:port
target			resolve A/AAAA of target			smtp:[target]
target:port		resolve A/AAAA of target and use port	smtp:[target]:port
mx:target		resolve MX of target				smtp:target
mx:target:port	resolve MX of target and use port	smtp:target:port
lmtp:target		resolve A/AAAA of target			lmtp:target
lmtp:target:port	resolve A/AAAA of target and use port	lmtp:target:port

target can also be an IPv4 or IPv6 address (an IPv6 address must be enclosed in []: [2001:DB8::]).
```

When there is proper input validation and existing database entries are migrated this function can be made much shorter again.

1831: Fix roundcube database env configuration r=mergify[bot] a=parisni

## What type of PR?

bug-fix

## What does this PR do?

Both roundcube and mailu admin website can be backed by postgres/mysql. Before this PR, the `DB_FLAVOR` is shared by both services. However, the other roundcube dedicated DB params are prefixed with `ROUNDCUBE_`. (eg: `ROUNDCUBE_DB_NAME`)
There is no reason to share the DB_FLAVOR for both: This PR makes them be considered independently to make things clear and avoid bugs.
Also, the roundcube_db_flavor and db_flavor are made separated in this PR. However for simplicity, the template generator bind them : roundcube_db_flavor = db_flavor. This makes the template generator UI more simple. I considered most of the time people want to have both roundcube and mailu share the same RDBMS.

Also, AFAIK the internal postgresql service is deprecated and will be removed in 1.9. This is why this PR does not integrate roundcube in postgres when the internal DB is choosen: in case of internal postgres, the roundcube is backed with sqlite.

Both documentation and setup website have been updated accordingly.
