Review connection id data type and allowed values on swagger

[italovalcy]

Hi,

Currently the connection ID is specified to be an Integer ranging from 1 to 10, which does not sounds reasonable. I think we should support creation of more than 10 "connections". Any reason to limit the number of connections?

Additionally maybe the connection ID should be generated by the controller, not provided by the user! Specially because the connection id is being used to persist data on database. I think we shouldn't rely on the user input to guarantee uniqueness of important fields like this.

What do you guys think?

@italovalcy I too don't think integers make a good connection IDs, because integers do not meet uniqueness properties we require. I also agree that the controller should generate connection IDs.

That is what I'm attempting in PR #225: POST /connection handler will generate a UUID to represent connection ID, and GET /connection/:connection_id and then DELETE /connection/:connection_id should use this generated ID. There are a couple of related issues mentioned there.

#225 made connection IDs integers, and removed the minimum and maximum limits. I believe that addresses this.
