Migrate from ujson to simplejson

The change updates the imports to use simplejson library and
monasca_api.common.rest instead of monasca_common.rest, since
it was moved to this project during the API's merge.

Temporarily set following jobs as non-voting:

* monasca-tempest-python3-influxdb
* build-monasca-docker-image
* publish-monasca-api-docker-image
