Modify HCAO build pipeline to include "added_for_HCA" tags

[paolaroncaglia]

As agreed with @dosumis , @zoependlington and Human Cell Atlas curators, I'm adding subset tags labelled "added_for_HCA" to CL, Uberon and EFO. We'll use these to ensure that all terms created for HCA are automatically retrieved when building HCAO. When the tags are all in (i.e. when https://github.com/obophenotype/cell-ontology/issues/826, https://github.com/obophenotype/uberon/issues/1700 and https://github.com/EBISPOT/efo/issues/920 are all committed and released in the respective ontologies), @dosumis and @zoependlington will modify the HCAO build pipeline. First try filter - Zoe has an example. Thank you both.

Update/note for self: As of today Feb 18th, the subset tag "added_for_HCA" has been

• added to CL (already released and in OLS)
• added to Uberon (already released and in OLS)
• added to EFO (already released and in OLS).

All is ready to include the tag in the pipeline.

Update: @zoependlington added the subset added_for_hca pipeline to the Makefile, so I'll close this ticket.
