Rewrite get_secgroup_uuids to avoid resource_by_refid

get_secgroup_uuids has changed in the following ways:
* No longer attempts to find a security group name via
  a resource_by_refid lookup. resource_by_refid only exists
  as a workaround for AWS compatibility resource which are
  not backed by an API. Usage of resource_by_refid should be
  avoided in native resources if at all possible.
* If the security group looks like a UUID, assume it is
  a UUID for a security group that exists
* Call client.list_security_groups only once, and only if
  there is a non-uuid security group specified
* Do not attempt to reduce duplicate security groups to a unique
  list. If that is important for resources it can be done in
  validation.
* Raise PhysicalResourceNotFound if name maps to no group
* Raise PhysicalResourceNameAmbiguity if name maps to more than one
  group

Use get_secgroup_uuids in Instance

Instance._get_security_groups_id serves the same
purpose as neutron.get_secgroup_uuids. This change switches
Instance to using get_secgroup_uuids instead.

Updating the test has the side-effect on getting full test
coverage on get_secgroup_uuids, albeit indirectly.

Managed Cloud compatibility for Cloud Servers

Make the Cloud Servers resource aware of the Managed Cloud automation.
The Cloud Servers resource should wait for the Managed Cloud automation

Fix server update attribute test

This is testing if an attribute not in the update_allowed_keys
results in UpdateReplace. Whilst this is true here, it's using
an attribute that is not a valid resource attribute. The only
valid resource attributes that I know of are:
(Properties, Metadata, UpdatePolicy, DeletionPolicy)

Just want to make sure we are testing the right thing.

Update install.sh to reflect recent oslo.db format

The previous sql_connection option has been deprecated and replaced
with the database.connection option in oslo:

[database]
connection = mysql://heat:heat@localhost/heat

The old option still works, but the default is only respected from
the new option, which is confusing if you're relying on the previous
behavior where specifying nothing got you the sql_connection default.
So update the installed config to remove the deprecated options.

Ensure autoscaling actions occur for percentage adjustment

Fixes bug 1251007

Previously if the AdjustmentType was set to PercentChangeInCapacity,
then depending on the choice of the instance group MinSize and the
scale-up policy ScalingAdjustment, no autoscaling actions may occur
even when the under-scaled alarm fires.

This situation occurred if:

   (MinSize * ScalingAdjustment / 100.0) < 1.0

in which case the group never get gets scaled up even if the under-
scaled alarm stays in the alarm state forever.

Now we follow the rounding rules used by AWS Autoscaling:

Add support for limiting and sorting stacks

This adds support to the stacks index call for limit, sort_keys,
sort_dir, and marker query parameters, allowing users of the API to
retrieve a subset of stacks.

With this commit, stacks are also sorted by created_at DESC by default.
