Commit 537a292674 introduced support
for having trunk named something other than master.
The name "master" is still hardcoded in the test-matrix, and in
the list of allowed branches. Adding support for an arbitrary
features file via DEVSTACK_GATE_FEATURE_MATRIX env variable.
The list of allowed branches is now parsed from the feature matrix.
