aws: Only store protocol numbers for ingress/egress rules on ACLs.

Users can input a limited number of protocol names (e.g. "tcp") as
inputs to network ACL rules, but the API only supports valid protocol
number:

http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml

Preserve the convenience of protocol names and simultaneously support
numbers by only writing numbers to the state file. Also use numbers
when hashing the rules, to keep everything consistent.
