Move hour_angle() and lst() methods from RA to coordinates #1385
Description
In the discussion related to #1310 it was agreed to move the RA.hour_angle() and RA.lst() methods into the coordinates class.
See here and commentary above for justification.
Moving these two methods into coordinates is not a completely trivial migration, since as mentioned there can be subtleties. It also seems reasonable to expect that these two methods should be available for non-Equatorial coordinate systems (e.g. Galactic) and that the appropriate transformations would be done.
For #1310, the methods and associated tests will just be dropped, with this issue providing the placeholder to reinstate them with Coordinates, probably as SphericalCoordinatesBase methods. The links into the 0.2.4 branch above provide the reference implementation. The 0.2.4 tests are here.

Given the discussion in #1418, I'm pushing this to the next version. We'll need to integrate it with the way of calculating LST, anyway.
