Enable testing for ruby 2.0/2.1 on travis.

Allow failures on 2.1 vmdb test suite.

Enable fast_finish so a PR is green without the required 2.1 vmdb suite:
"Now, a build will finish as soon as a job has failed, or when the only jobs left allow failures."

Merge pull request #960 from h-kataria/added_missing_route_for_group_update

Added 'group_update' missing route to catalog explorer.
Fixed rendering issues after the upload of Sysprep Answer File

Clicking on Upload resulted in many Provisioning dialog rendering issues such as -
1. Form buttons (submit/cancel) were not showing up effectively inhibiting provisioning
2. Layout abruptly switched from explorer to non-explorer

Other than the above rendering issues, also fixed a routing error and a
crash that was originally reported in the BZ.
