1. Deploy 2 gateways on different nodes, then check for multi-path.
To add another gateway, only "roles" need to be changed in job yaml.
2. Create "n" nvmeof namespaces, configured by 'namespaces_count'
3. Rename qa/suites/rbd/nvmeof/cluster/fixed-3.yaml to fixed-4.yaml
which contains 2 gateways and 2 initiators.

This is v2 of the rbd/nvmeof test: It deploys 1 gateway and 1 initiator.
Then does basic verification on nvme commands and runs fio.
This commit creates:
1. qa/tasks/nvmeof.py: adds a new 'Nvmeof' task which deploys
the gateway and shares config with the initiator hosts.
Sharing config was previously done by 'nvmeof_gateway_cfg' task
in qa/tasks/cephadm.py (that task is removed in this commit).
2. qa/workunits/rbd/nvmeof_basic_tests.sh:
Runs nvme commands (discovery, connect, connect-all, disconnect-all,
and list-subsys) and does basic verification of the output.
3. qa/workunits/rbd/nvmeof_fio_test.sh:
Runs fio command. Also runs iostat in parallel if IOSTAT_INTERVAL
variable is set. This variable configures the delay between each iostat
print.
nvmeof-cli upgrade from v0.0.6 to v0.0.7 introduced major changes
to all nvmeof commands. This commit changes v0.0.6 commands to
v0.0.7 in qa/workunits/rbd/nvmeof_initiator.sh
