Multiscope to main branch

[costero-e]

Hello,
as we are already implementing beacons with this accepted work in filtering terms scope, which now becomes an array of scopes, I was feeling the need to make it official, hence I am merging it to main branch. Also, I think it is good to already show it in main branch for further discussions.
Let me know what you think. Thank you.

"Entry types affected by this filter" since then we accommodate for query aggregation.

... and making this multi-scope clear by example:

examples:
  - - individual
    - biosample
    - analysis
    - run
    - genomicVariation
  - - biosample

[mbaudis]

+1, with wish for change in wording (see inline comment).

Also, for a clean schema it would be good if the possible scopes could be derived from somewhere (i.e. defined in the model & retrieved...). Or we could make it a hard coded enum - but these are, comments, not requirements.

The scopes are entryTypes, So beacon provider may have its own types and associated filters...

examples:
   - - individual
     - biosample
     - analysis
     - run
     - genomicVariation
   - - biosample

I am not sure... is it valid???

I would prefer:

examples:
  - [individual, biosample, analysis, run, genomicVariation]
  - [biosample]

@redmitry

1. Yes; therefore it would be good to have some way to retrieve the local entry types, as the maximum set of optional values. But again, this was just a thought and I don't want to expand on this ...
2. I prefer to stay in one style (although sometimes it is easier to stay in one line if few short elements). There is even an option to have an empty indent to make the list more visible... Again, more of a comment...

examples:
   - 
     - individual
     - biosample
     - analysis
     - run
     - genomicVariation
   - 
     - biosample

(I find this version more confusing since especially w/ 2 space indentation it doesn't look that clear - but YMMV).

Thank you @mbaudis and @redmitry . Please, review #119 where I have applied the changes suggested and then we will be able to merge them here, too. Thank you.

[costero-e]

Changes you requested have been applied @mbaudis. If you want to review again. Thank you.
