[17.0] [IMP] storage: Remove dependency on server_environment

[yankinmax]

This is a forward-port of:

• [16.0] [IMP] fs_storage: Remove dependancy on server_environment #627

With the applied fixes introduced in:

• [16.0][FIX] fs_attachment,fs_attachment_s3,fs_storage,fs_storage_backup: fix server_environment split migration and add install/uninstall hooks #653
• [17.0][BKP] server_environment: Preserve not env managed data server-env#286

Hello @etobella @lmignon @ivantodorovich
In this PR I've cherry-picked the commits from merged 16.0 PR.
I squashed the commits that are related to one module split.
I've added new commits for storage_backend* modules.
The upgrade scripts and uninstall hooks are added for each module.
image_tag split is handled separately, because it doesn't introduce any server_env_fields override, so only need the upgrade script:

• [17.0][ADD] image_tag_environment: make server_environment an optional dependency #580

Thank you for the FWP

Thanks!

Hmm are we sure we want to make these modules auto-install?
That means that if I still have server env installed for a different app (eg: mail) this module will be installed as well w/o any reason.
Since the migration is taking care of installing the modules I would say this has to change.
Am I missing any particular reason to keep auto-install?
