Now raw data is gathered on the backend and rendered on the frontend.

This validates application name asynchronously on the server. Validation is synced with namespace select :)

This is because name does not make sense in the YAML upload form.

Now variables are in variables.css in frontend directory. Previously they were in assets, which was wrong because it caused copy to production image.

This PR implements column layout for the replica set list view. The
layout is implemented through a directive that puts its transcluded
elements into a column layout.

There's some algorithmic code in this PR, so please comment if something
is not tested or easy to understand.

Please also verify on your machines that this works correctly.

* this is a refactoring change - no functional changes
* added missing tests
* added missing module dependency (tests found it)
* this is a prerequisite PR for future work on the card

They just have been recently added. It allows us to delete some code.

This change adds linter for styles to the project and updates all styles
to conform with the default set of rules.

This should help us maintain a little bit more consistency in our
styles.

This is because new compiler version has new type inference, which is
more strict.

- Now zero state view is stretched to full screen

The UI is as specified in the mocks, except for the names of the fields.
I decided to go with what is in the API.

Everything is extensively tested. I also added some tests for previously
untested cases.

The reason for doing this is the fact that namespace selection does not
make sense in case of uploading YAML. This should be only in deploy from
settings.

Added check to prevent display of replica set list page when there are no replica sets.
