[COMMON] Add and run pre-commit linters via tox

- create a .pre-commit-config.yaml configuration file with
  * gitlint
  * trailing blanks linter
  * tabs removal linter
    - exclude .git folder from it
    - exclude Makefiles since tabs are mandatory by default in them
- create a tox pre-commit profile to run it from tox
  note gitlint is not runnable at this pre-commit stage
- create pre-commit-install and pre-commit-uninstall tox profiles to
  (un)install hooks locally and (un)perform tests at each "git commit"
  call (i.e. without calling manually the pre-commit tox profile)
- precise pre-commit stages/types in the pre-commit configuration file
  so that hooks are installed correctly. This avoids messages about
  skipped tests when they are run at a wrong stage.
