Certain nova containers require more locked memory that the default limit of 16KiB.
Increase the default memlock to 64MiB via ``DockerNovaComputeUlimit``.
As this is only a maximum limit and not a pre-allocatiosn this will not
increase the memory requirements for all nova containers. To date the only
container to require this is nova_cell_v2_discover_hosts which is short lived.
