Default SG rules for the Security Group "Default"

Added in the API os-security-group-default-rules

This allows create, delete, list, and get (of individual rules) for
rules that will be pre-populated into the Security Group "default"
that is populated in all projects on creation.

These rules will not be applied retroactively, as it is designed
to allow the creation of a "reasonable" base-line set of sg rules.

The new rules live in a separate table that mirrors the relevant
structures of the security_group_rules table.

Added unit tests/API samples for the new API calls
