Write a deleteFhirServer function to remove a DB config

[bamader]

Description:

Write a function to delete a FHIR server and its config from the database. This function should remove the corresponding DB row from the postgres instance as well as remove the row from the table (which should happen automatically since we’ll want to dynamically populate the table anyway). Note that this delete function will need to be hooked up to the hover-over Delete button on the table, as well as the Delete button in the Edit view.

Acceptance Criteria:

A delete function is written and can be called from the front end
