Add Pagination, Filtering and Sorting to endpoint Get Bounties for Phase

[fvalentiner]

Context

Bounty: https://community.sphinx.chat/bounty/2008

We need to add pagination, filtering and sorting to the get bounties for phase endpoint.
GET /features/{feature_uuid}/phase/{phase_uuid}/bounty

Design

Copy functionality from /gobounties/all
Make sure you handle all this query parameters
limit=10
&sortBy=created
&search=
&page=1
&resetPage=true
&Open=true
&Assigned=false
&Completed=false
&Paid=false
&languages=

The functionality to copy from the endpoint /gobounties/all is in the handler bountyHandler.GetAllBounties

• Make sure you are running posgresql locally
• Create file .env with the following content
  PORT=5005
  DATABASE_URL=postgres://postgres:asdf@localhost:5432/ebdb?sslmode=disable

Change DATABASE_URL to connect to your local DB (it could be an empty db)

• Run "go run ." to run the backend API that connects to the DB and creates the objects

Your job is to create the routes, handler functions and db changes in order for the test to pass.

Acceptance Criteria

• I have created bounties and put them on each of the bounty states [Open], [Assigned], [Completed], [Paid]
• I have created bounties in different languages [Golang], [Typescript]
• I have tested each of the query parameters [limit], [sortBy], [search], [page], [resetPage], [Open], [Assigned], [Completed], [Paid] and [languages
• I have tested several values for each filter parameter
• I can submit a pr within 6 hours of taking the bounty
