Update URLs on the ClubEndpoint to use club ids rather than club names

[bfbachmann]

• Take a look at bounce/server/api/clubs.py
• You'll have to update the __uri__ on ClubEndpoint and all it's methods like get, put, delete to query the database based on the club ID rather than it's name
• This might also require updating some of the queries in functions like update in bounce/db/club.py
• I'd recommend using Postman to make test HTTP requests
