Basic networking in Neutron - max VLAN should be 4094, not 4095

[Eugen]

This bug tracker is for errors with the documentation, use the following as a template and remove or add fields as you see fit. Convert [ ] into [x] to check boxes:

- [x] This doc is inaccurate in this way: It reads "Each VLAN has an associated numerical ID, between 1 and 4095", but 4095 is reserved and should not be used for a VLAN.
- [ ] This is a doc addition request.
- [ ] I have a fix to the document that I can paste below including example: input and output.
