Drop nova-multiattach job

The dependent tempest change enables the volume multiattach
tests in the tempest-full and tempest-slow jobs, on which
nova already gates, which allows us to drop the special
nova-multiattach job which is mostly redundant test coverage
of the other tempest.api.compute.* tests, and allows us to
run one fewer job on nova/cinder/tempest changes in Stein.

The docs are updated to reflect the source of the testing
now.

Also depends on cinder dropping its usage of the nova-multiattach
job before we can drop the job definition from nova.
