• This PR adds methods to retrieve named states via the move_group class.
• It also adds the corresponding python bindings for these methods.
• I also allows for the warehouse DB host to be specified from a parameter.

Heya,

Actually I was thinking of adding this request myself after I found out Shadow has their own patchset which they provide for their users. So a big +1 to have this request here.

However, the branch, as it is, is quite a mess...

(1) Could you please use git rebase to get rid of all the merge commits? This is pretty straight forward and I already did this once locally last month...

(2) Could you please squash the fixup commits together with the commits introducing the code? At least 0f1a9f7 , 5f9bbac and c4a1f51 should definitely be only one commit.

The same goes for 056bf8b and 997d8ba .

sorry, I mixed up commit ids, just updated the ids in the previous comment.

Hi @v4hn. Yes, sorry for the mess. I wasn't sure if this PR would be of interest. I'm glad it is. I will tidy up the commits.
