to be able to debug running envs more easily, in particular in customer environments.

Closes [RUNTIME-497](https://bonitasoft.atlassian.net/browse/RUNTIME-497)

This change is done to avoid conflicts when building docker image in PRs (e.g. PR tag a
7.13.0-SNAPSHOT and dev does the same at the same time)

Add a new option `-t` on the `build.sh`. It takes in input a tag name
and it overrides the default tag (`bonitasoft/...:7.x.y-SNAPSHOT`)

This simplifies the build and push of image on `quay` (it avoid using an
intermediate tag)

For security reasons, it's better to not print any configured
credentials on startup.

as the DNS records for the pools will no longer be provided at all

```
This service is deprecated. This means it is no longer maintained, and new HKPS certificates will not be issued. Service reliability should not be expected.

Update 2021-06-21: Due to even more GDPR takedown requests, the DNS records for the pool will no longer be provided at all.

Closes [RUNTIME-223](https://bonitasoft.atlassian.net/browse/RUNTIME-223)

More precisely from another directory, instead of requiring to be
in root Bonita directory to launch start/stop-bonita.sh/.bat 

Closes [RUNTIME-297](https://bonitasoft.atlassian.net/browse/RUNTIME-297)

If we directly publish the image to `bonitasoft-rd` quay organization,
it means we do not need to update the subscription DockeFile in order
to push those images to `bonitasoft` organization.

Adapt docker build file to be able to build other version than SNAPSHOT
using local file. Also drop the possibility to build sp image from an
external url. (no more sha256 needed)
