Regression in simple extra_specs matching in compute_capabilities_filter

[Mark McLoughlin]

Before https://review.openstack.org/#/c/8089/, you could do something like:

   sudo nova-manage instance_type set_key nokvm.tiny hypervisor_type QEMU

and only compute hosts whose "hypervisor_type" was reported as "QEMU" would pass the host filter.

i.e. we did simple string matching of extra specs against host capabilities

Now, if no operator is present in extra specs, we no longer do string matching and just say that the extra spec is satisfied.

This is unintentional. The previous behaviour should be retained.
