Error decoding json payload json: cannot unmarshal number into Go struct field JobResponse.id of type int

Problem

Users are experiencing an integer overflow whilst decoding the job response on 32-bit architectures. Runner uses the type int to represent the Job ID, which is 32-bits wide on a 32-bit arch. It should be using int64, as we're expected to reach Job IDs above math.MaxInt32 soon.

Proposed Solution

Fix the following structs in network.go to use int64 for the ID. The IDs in these structs are all Job/Build IDs.

• UpdateJobInfo
• JobResponse
• Dependency
• JobCredentials
