Add CLI args for skipping build and disabling fail fast
This is useful for people with slow docker builds. I also added a flag to disable FAIL_FAST, will might be useful for parallel runs. This still doesn't work properly though, because of resources not getting cleaned up.
I also changed the filter to come from cli args the proper way instead of manually extracting from argv.
positional arguments:
filter filter tests by name
options:
-h, --help show this help message and exit
--no-build skip building the container image
--run-all run all tests instead of stopping at first failure
