test/dashboard: only test enabled python bindings

we should test the python version of MGR_PYTHON_VERSION_MAJOR, if we are
testing both py2.7 and py3, we are preparing for distributing dashboard
as a separated package independent of ceph-mgr.

restructure the dashboard tests as 2 matrices, so we have 2*2 tests for
coverage and lint respectively.
