Fix docstring for SecurityGroupHandlerBase

Include name in a primitive Instance.

This ensures that the name of an instance will be present in the result
of jsonutils.to_primitive(Instance).  The name isn't a column.  It's a
property that gets generated dynamically by the Instance class.

Convert reboot_instance to take a full instance.

Convert the reboot_instance method in the compute rpc API to take a full
instance via rpc instead of just the instance UUID.  This cuts down on
database access needed by nova-compute.

Don't use rpc to lock/unlock an instance.

Instead of converting this method to send a full instance over rpc
instead of just an instance UUID, this patch removes the usage of rpc
for this operation entirely.  All it's doing is a database update.  RPC
is expensive, so cut out the middle-man.

One functional difference with this approach is that the db update is
now synchronous on the API node, instead of kicking off an async message
to a compute node to handle it.  This seems fine, though.

Send a full instance via rpc for (un)pause_instance.

Change the pause_instance and unpause_instance methods of the compute
rpc API to take a full instance over rpc instead of just the instance
UUID.  This cuts down on database access needed by nova-compute.

Send a full instance via rpc for suspend_instance.

Change the suspend_instance method of the compute rpc API to take a full
instance over rpc instead of just the instance UUID.  This cuts down on
database access needed by nova-compute.

Send a full instance via rpc for get_console_output.

Change the get_console_output method of the compute rpc API to take a
full instance over rpc instead of just the instance UUID.  This cuts
down on database access needed by nova-compute.

Send a full instance via rpc for add_fixed_ip_to_instance.

Change the add_fixed_ip_to_instance method of the compute rpc API to take a
full instance over rpc instead of just the instance UUID.  This cuts
down on database access needed by nova-compute.

Send a full instance via rpc for attach_volume.

Change the attach_volume method of the compute rpc API to take a
full instance over rpc instead of just the instance UUID.  This cuts
down on database access needed by nova-compute.

Remove unused scheduler functions

* get_service_capabilities
* get_host_list
* host_service_caps_stale
* delete_expired_host_services

The functions were introduced in d328ddcadb24d1b1961bd05a7676bc8f54b6776f
but are currently unused outside of nova.tests
