Move galaxy.web.stack.database_heartbeat into galaxy.model - since it was the only thing in galaxy.web.stack that used galaxy.model at all and it didn't import anything else from galaxy.web.stack.
Once that was done, I refactored this whole package (galaxy.web.stack) into galaxy.web_stack. It doesn't use the framework setup or exported by the base galaxy.web package so it wouldn't seem to belong there. It also has very different dependencies than the rest of that. And finally and most importantly, this elimiantes almost all dependency from galaxy.jobs and galaxy.tools and galaxy.workflows to anything in galaxy.web.

Fixes https://github.com/galaxyproject/planemo/issues/939 (once released
as galaxy-lib)
This is to update galaxy.yml.sample and galaxy_options.rst to be
consistent with the latest update to config_schema.yml (#5651edc)
(generated with make config-rebuild)
This was meant for #7110 I think, I'm not sure why I didn't land up actually including it. Needed now for extended metadata collection using galaxy-job-execution package on Pulsar.
