all visits related to particpant endpoint

[MikeyManoguerra]

/api/participants/<id>/visits

this endpoint is retrieve only. do not allow post.

This endpoint will take the participant_id and return all visits associated with them.

make sure each visit is not redundantly populated with all the visit information

Should the foreign keys to Program and Service be embedded, left as foreign keys, or something else?

[MikeyManoguerra]

let's populate with ServiceforProgramSerializer
and ProgramSerializer (but leave out a nested services array)

we do not want the populated participant object, just the FK.

Just use viewsets.Viewset and define retrieve as this is a read only endpoint

finally, you can add new classes in the /visits/ directory files, no need to create a completely new folder
