Replace size comparison with size checker methods

Currently repository size checking is only happening at EE,
and is coupled with attribute names heavily.
By extracting related calculations into RepositorySizeChecker,
they are decoupled from attribute names,
and can later be reused on Snippet which has different attribute names.

This is moved to FOSS level, same level as snippet checking.
