Sean Mooney b3f8815720 Disable the heal instance info cache periodic task
The _heal_instance_info_cache periodic task predates
the introduction of the server external events API
which is now the canonical way to refresh the cache.

This change updates the default value of
``[compute]heal_instance_info_cache_interval``
to -1 disabling it by default.

The nova-ovs-hybrid-plug job is extended to test the
legacy configuration value and the config override is removed
from nova-next

OpenStack Nova provides a cloud computing fabric controller, supporting a wide
variety of compute technologies, including: libvirt (KVM, Xen, LXC and more),
VMware and OpenStack Ironic.

Use the following resources to learn more.

API
---

To learn how to use Nova's API, consult the documentation available online at:

- `Compute API Guide <https://docs.openstack.org/api-guide/compute/>`__
- `Compute API Reference <https://docs.openstack.org/api-ref/compute/>`__

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

- `OpenStack for App Developers <https://www.openstack.org/appdev/>`__
- `Development resources for OpenStack clouds
  <https://developer.openstack.org/>`__

Operators
---------

To learn how to deploy and configure OpenStack Nova, consult the documentation
available online at:

- `OpenStack Nova <https://docs.openstack.org/nova/>`__

In the unfortunate event that bugs are discovered, they should be reported to
the appropriate bug tracker. If you obtained the software from a 3rd party
operating system vendor, it is often wise to use their own bug tracker for
reporting problems. In all other cases use the master OpenStack bug tracker,
available at:

- `Bug Tracker <https://bugs.launchpad.net/nova>`__

Developers
----------

For information on how to contribute to Nova, please see the contents of the
CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst
file, and pass all unit tests.

To understand better the processes that the team is using, please refer to the
`Process document <https://docs.openstack.org/nova/latest/contributor/process.html>`__.

Further developer focused documentation is available at:

- `Official Nova Documentation <https://docs.openstack.org/nova/>`__
- `Official Client Documentation
  <https://docs.openstack.org/python-novaclient/>`__

Other Information
-----------------

During each `Summit`_ and `Project Team Gathering`_, we agree on what the whole
community wants to focus on for the upcoming release. The plans for nova can
be found at:

- `Nova Specs <http://specs.openstack.org/openstack/nova-specs/>`__
