Filesystem logic refactor, improved defaults for cache tenancy (#42)

* refactor FilesystemTenancyBootstrapper

* clean up tests and improve coverage

* minor maintenance mode changes

* Improve tenants:migrate --skip-failing logic

* make tenants:migrate output consistently formatted

* minor RootUrlBootstrapper + misc changes

* cache bootstrapper-related improvements

* Fix code style (php-cs-fixer)

* misc refactor

* Fix code style (php-cs-fixer)

* add %original_storage_path% to fs bootstrapper, improve default config for cache

* rename method

* inject concrete implementations where needed instead of abstracts

* Fix code style (php-cs-fixer)

* refactor DealsWithTenantSymlinks

* remove obsolete phpstan ignore
