samples: lightdb_stream: add twister runtime test with pytest

mniestroj commented 2 years ago

Add basic pytest runtime test, which runs:

$ goliothctl $GOLIOTHCTL_OPTS stream listen $GOLIOTH_DEVICE_NAME

and verifies if temperature measurements are received. Right now an arbitrary number of 10 events is expected, before considering test as passed.

TODO:

[ ] document which environment variables should be set before running this by twister with runtime test (not just build time)
[ ] figure out if there is a better way of passing credentials than via environment variables fetched from Kconfig
[ ] add runtime tests to CI, so that this code actually gets used
