feat: allow to use single web instance for all repositories (#114)

* Allow to use single web instance for any repository

* some improvements

* drop includes from user home directory, introduce new variables to docker

The old solution didn't actually work as expected, because devtools
configuration belongs to filesystem (as well as sudo one), so it was
still required to run setup command.

In order to handle additional repositories, the POSTSETUP and PRESETUP
commands variables have been introduced. FAQ has been updated as well

* raise 404 in case if repository is unknown
