Data management application

Some clean up yet to be done, but I think it's time to start thinking about merging this in and getting this deployed out.

Status (will update our internal tools too):
- [x] Raw request view using Ace code editor
- [x] Request "builder" view (it uses a jsoneditor for now, eventually we can do specifically tailored query building that interacts with the metadata and such)
- [x] Two-way binding of raw and builder view... I put this as it's own point because most of getting the builder view working was this.
- [x] Raw response view using Ace code editor (it is read only of course but the editor allows collapsing objects and such)
- [x] Saml authentication setup (I still need to tweak some of the configs, but there's not much to do here)

Todo:
- [ ] Add header that Lightblue login module will accept in order to impersonate requests as the logged in user

Beyond that, I have many nonessential-but-potentially-nice enhancement ideas as issues on my fork: https://github.com/alechenninger/lightblue-applications/issues
