Web UI tests were marked as tier1 tests.
The tier system is intended to be used together with CI system
to make sure the more complicated tests are being run only
when all of the basic functionality is working.
The system is using pytest's marker system. E.g. an invocation of
all tier1 tests with listing will look like:
$ py.test -v -m tier1 ipatests
or in case of out of tree tests:
$ ipa-run-tests -m tier1
