Fix ssh key specification in the README.rst

The ssh public key entries starts with key type
specifier like 'ssh-rsa', but the puppet module which consuming the ssh_key
 expects only the key part.

Also switching to the id_rsa.pub in the example, because usually it
contains just only one public key, what the users usually pushes to the servers.

The authorized_keys file is for the keys accepted by the user's machine
itself.

Deprecate API_RATE_LIMIT setting for Tempest runs

The default value for api_rate_limit in nova.conf has been False since
Havana per commit cfdc59860ef1482e3b064f90f719ec9e484590ce.

Devstack commit f617a2ddddf7d8f759ff3ca5d66a133b124eeb42 removes the
API_RATE_LIMIT variable.

Since we're not going to backport the devstack change to the stable
branches, this patch adds a TODO in the script to remove the variable
when stable/juno is our oldest supported branch.

Set required devstack variables for Ironic+grenade

When sideways migrating from the fake nova driver, do not attempt to
exercise the base side of Grenade using Tempest and Javelin.  Also,
bump the number of VMs enrolled in the Ironic inventory to 3 to
facilitate Tempest concurrency.

turn off clean log checking

The effort to clean out the issues in the logs in OpenStack has
largely stalled, and the impact of this is currently just a lot more
spurious failures that aren't getting looked at. Also it's kind of a
layer violation given that the checker is in Tempest but called from
devstack-gate.

The number of logs that were actually considered clean is actually
very small (only 4 or 5 out of 30), so this wasn't really preventing
many new bugs from entering. Removing it will decrease failure rates
for tempest runs which otherwise passed.

Don't use ephemeral volumes for Ironic agent driver

The agent driver (unfortunately) does not support ephemeral volumes
yet. This change sets ephemeral volume size to 0, which is checked
by Tempest when testing ephemeral support.

Longer build timeout for Ironic agent driver

Does what it says; the agent driver is currently a bit slower than
the PXE driver, for a number of reasons.

Install PyYaml for test-matrix.py

We have an implicit dependency on PyYaml in test-matrix.py, install it
prior to running test-matrix.py.
