lxd driver broken due to upstream changes in nova

[Logan V]

In openstack-ansible we began seeing failures on our nova-lxd test due to: http://logs.openstack.org/75/500575/2/check/gate-openstack-ansible-os_nova-ansible-func_lxd-ubuntu-xenial/605dfde/logs/host/nova/nova-compute.log.txt.gz#_2017-09-08_23_17_17_074 several days ago. It seems like the 'max_mem_kb' along with several other attributes were removed here https://review.openstack.org/#/c/471146/ which has broken the lxd driver.
