Enable Heat docker resource by default

https://blueprints.launchpad.net/mos/+spec/murano-docker-based-applications https://blueprints.launchpad.net/mos/+spec/heat-docker-resource-by-default

Docker resource is disabled by default for Heat, current Blueprint is required to enable this resource for using it by Murano without additional deployment workarounds.

Problem description

MOX 2.3 already contains a bunch of Murano Docker-based applications. These apps are being forward-ported to MOX 3.0. At this moment these applications are not available in MOS. To avoid further differences between MOS and MOX, we’re going to add Docker-based apps to MOS 6.1.

Proposed change

Currently docker resource is placed in Heat contrib directory and can not be used without installation and restarting Heat services. These changes adds ability to install docker resource on deployment step, so it makes docker resource available for Heat on first launch.

Alternatives

None

Data model impact

It does not require any changes in Data Base.

REST API impact

Upgrade impact

Several new packages should be installed (heat_docker and docker requirements)

Security impact

Performance Impact

Other deployer impact

Requires installation of addtional packages and small changes in manifests, which need to configure the right path to docker files.
