Fix race condition in device tag testing

Device tag tests (test_device_tagging.py) has hard coded
sleep with default cache time of metadata service. That cache
time is configurable on nova side (metadata_cache_expiration).

So instead of sleep with hard code value, we should go with the wait
loop to fetch the metadata info for verification. For safer side,
build_timeout is being used as max time to fetch the expected metadata
info otherwise test will fail with timeout.
