Add JavaScript gate jobs to LBaaS dashboard

The LBaaS v2 dashboard is Angular based. It needs JavaScript
unit tests and linting in the gate. Add them non-voting
initially.

These tests will fail until Ia0231f44b36cf5263ed5efbbdfa42ad9cf63c4a0
is merged, but would like to proceed anyway, since jobs will be
non-voting initially anyway.
