maas: module: Obtain fabric ID from CIDR

MaaS subnet update requires specifying the correct fabric via reclass,
which we used to hardcode in our reclass model.
However, fabric index numbers are not deterministic, especially when
using a fabric other than 'fabric-0'.

Update MaaS custom py module to determine fabric name/ID on the
fly, based on CIDR matching (assuming we don't have CIDR conflicts).

This change maintains backwards compatibility:
- if fabric is specified via reclass model, it will be used as-is;
- if fabric is not specified via reclass model, we try to deduce it
  based on CIDR; if no match is found, the old default ('') is used;
