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

Provide way to pass rxtx factor to quantum

This patch adds a config option quantum_extension_sync_interval which by
default is set to 600 seconds. After 600 seconds the next time nova needs to
create a resource in quantum it will requery quantum for the extensions
that it has loaded.

Hopefully in Havana something smarter will be implemented rather than using
time sync. I believe a better way to implement this would be to have each
compute host keep a pool of persistant sockets open to quantum for it to
communicate over. Resync'ing then would only happen if the connection to
quantum broke because quantum needs to be restarted in order to change the
extensions it is using

Change CIDR column size on migration version 149

As discussed in review https://review.openstack.org/#/c/22238 cidr column needs
up to 43 characters in some cases, and this should be upgrade to avoid data get
lost.
