In case /var/lib/nova/instances resides on NFS we have seen migrations
failing with 'Failed to get "write" lock - Is another process using the
image' errors.
This has been tracked down to grace/lease timeouts not having expired
before attempting the migration/evacuate, so in this cases it might be
desirable to delay the nova evacuate call to give the storage time to
release the locks.

In all the chaos of complicated patch unentanglement and rebasing,
I forgot to actually even syntax-check the thing :-(

Apache-2.0 is the recommended license for OpenStack Big Tent
projects (see https://governance.openstack.org/reference/licensing.html)
and this simplifies the licensing of the overall git repo
quite a bit by removing an exception clause.

Closes-Bug: #1564844
Make it clearer what the risks of not using shared storage are.
Information is based on:
http://docs.openstack.org/user-guide-admin/cli_nova_evacuate.html
which says "The command rebuilds the instance from the original image or
volume" but later says that "To preserve the user disk data on the
evacuated server, deploy Compute with a shared file system" and then use
--on-shared-storage.

These can be quite useful in some setups.
This depends on https://github.com/ClusterLabs/fence-agents/pull/37

When no evacuation has been done yet, we're spamming syslog with:
Could not query value of evacuate: attribute does not exist
So let's just filter this out, since it's known to be expected on
initial setup.
As this requires a bashism, also move the script to use bash.

attrd_updater deprecated usage of -v a long time ago in favour of -U:
927660ba0c
so change the agent to use the documented option.

attrd_updater -D doesn't remove attributes; it just sets them to the
empty string. Make sure this is handled correctly in case anyone
invokes attrd_updater manually in order to mark a host as no longer
needing evacuation.

OCF RAs are not meant to be run directly, so for consistency with the
other RAs in this repo, remove the executable bits from these two files.

This requires the same fix to be applied to fence_compute:
https://github.com/ClusterLabs/fence-agents/pull/27
and is a more complete version of
33154a6680
which only patched NovaEvacuate and not NovaCompute.
