Configure "reserved_host_memory_mb" attribute to support bare metal

Browse Source 
The "reserved_host_memory_mb" attribute is default to 512MB when not
setting, it will make flavor match failed, so for bare metal service,
we need to set it to "0", no need to reserve host memory.

* `openstack["compute"]["config"]["resize_confirm_window"]` - Automatically confirm resizes after N seconds, Set to 0 to disable (default is 0)

* `openstack["compute"]["config"]["disk_cachemodes"]` - Cachemodes to use for different disk types e.g: "file=directsync,block=none". Valid cache values are "default", "none", "writethrough", "writeback", "directsync" and "unsafe".
* `openstack["compute"]["config"]["live_migration_retry_count"]` - Number of 1 second retries needed in live_migration
* `openstack["compute"]["config"]["flat_injected"]` - Whether to attempt to inject network setup into guest. Used by config_drive support.
