Swagger: "size" field on "repository" type needs to be int64

We have a repository which have the following size field:

#!json

"size": 3002598939,

This value is too big for an integer in Java. The repository is large because it uses LFS.

This is not supported by the current Swagger definition, since it looks like this:

#!json

"size": {
              "type": "integer"
            },

The definition needs to be changed to:

#!json

"size": {
              "type": "integer",
              "format": "int64"
            },
