feat: implement caching (#40)

* chore(docker-compose): add redis

* connect to redis and do something

* refactor(usercache): build the redis key with string builder

* refactor(usercache): change naming

* feat(usersrv): add caching for  CheckIfUserIsActivated

* refactor(e2e): handle errors consistently while setting up dbs

* refactor(usercache): set custom ttl for cache

* fixup! refactor(usercache): set custom ttl for cache

* feat(usersrv): actually cache things

* fixup! feat(usersrv): actually cache things

* refactor: update redis connector

* fixup! refactor: update redis connector

* refactor(e2e): connect to redis via it's own helper function

* refactor(usersrv): make linter happy again

* refactor(e2e): refactor, naming mainly

* e2e: reformat

* fix(e2e): stop redis on tests end

* refactor(e2e): setup tests deps in less lines

* refactor(e2e): renaming
