Populate the memory limits of functions in the REST API

[alexellis]

Expected Behaviour

When users list or query functions from the REST API, then the memory limits set on the functions should be returned in the JSON response.

Current Behaviour

They are being accepted upon deployment, but not being populated when querying.

Given how long has passed since you volunteered to help, this issue is now fair game for anyone who wants to contribute.

Nobody is working on this at present.

@Shikachuu I don't think we have any CPU limits at this stage, so this just covers memory being populated back again from what was inputted.
