Create a component to submit the Dataflow job to compute embeddings for code search (#324) 

* Create a component to submit the Dataflow job to compute embeddings for code search.

* Update Beam to 2.8.0
* Remove nmslib from Apache beam requirements.txt; its not needed and appears
  to have problems installing on the Dataflow workers.

* Spacy download was failing on Dataflow workers; reinstalling the spacy
  package as a pip package appears to fix this.

* Fix some bugs in the workflow for building the Docker images.

* * Split requirements.txt into separate requirements for the Dataflow
  workers and the UI.

* We don't want to install unnecessary dependencies in the Dataflow workers.
  Some unnecessary dependencies; e.g. nmslib were also having problems
  being installed in the workers.
