Add Merge functionality to Voyager

[allanbolipata]

We need to add a feature that lets CAS merge projects that can be uploaded to portal.

Initial requirements:

1. From labHeadName or labHeadEmail, get all requests associated with it
2. Merge into cbioportal instance e-mail address without the @mskcc.org, prepending "set_" to it
   • Use either merge script from https://github.com/mskcc/roslin-internal-services/tree/master/cbioportal_merge or something similar
3. Figure out how to incorporate legacy merged projects
   • Use old MongoDB? Create new DB? Run old projects through Voyager again?
4. Have it post to JIRA

The merge script in no. 2 could work as-is, but it hasn't been touched for half a year and would need some review. Since I wrote it, I'm happy to look it over before we start this effort.

@songt please add any info as needed.
