Remove all container zanata ui dependencies

Frontend containers directory only
ZNTA-1604 needs to be verified and merged before I can start this task

Refactoring of css classes/ids will be done as the branches are merged into master as the classes are used between branches.
They need to be refactored so they follow the bootstrap way of using hyphens instead of camel case.
This reduces the amount of refactoring needing during ZNTA-1606 (removing the last of atomic css from frontend)
As the subbranches here get merged in, I have noticed that little tweaks need to be made so that master looks tidy and polished. I am making these changes as I come across them.
