ICSHWI-10969: Replace metadata.yml with metadata.json

See merge request !105

Note that we need to sort the keys in order to ensure that the output
json data is consistent between runs.

ICSHWI-10917: Remove ENGINEER from deployment

See merge request !104

Remove cell mode from the deployment tool

See merge request !103

Cell mode has previously only been allowed for require < 4.0.0.
During the current maintenence window, we are removing it completely.
Most of this is simply modifying the molecule setups.

Unpin the dependent roles

See merge request !102

ICS-418: Always force clone of IOC repositories

See merge request !101

Note that we will shortly be removing cell mode support entirely, so this
is a more minor change than it appears.

See 365d604d
and https://jira.esss.lu.se/browse/ICSHWI-6668 for more context.

ICSHWI-9859: Support reading ioc.json

See merge request !100

ioc-exporter needs to support reading from `ioc.json` too

We will migrate away from having the IOC metadata in YAML format to
having it in JSON with the introduction of the IOC templating tool.

ICSHWI-9715: Bumped role-ioc-exporter version to 0.4.0

See merge request !99

ICSHWI-9691 Clear elevated capabilities from non-realtime IOCs

See merge request !98

ICSHWI-9676 Use urlsplit instead of custom regex_replace

See merge request !97

We still have to add the capabilities to the service template though
to be backwards compatible with older deployments; deploying a new IOC with
a new service template affects *all* the IOCs deployed on the host

There was some escaping problem with the regex that only showed up
during live ansible runs; molecule did not complain at all.
Even though we could just remove the escaping since it is not really necessary
it is still better to use the `urlsplit` filter that is a dedicated URL
manipulating function.

ICSHWI-9594: Bumped role-ioc-exporter version to 0.3.4

See merge request !96

ICSHWI-9541: Mount: absent might not unmount share

See merge request !95

It won't unmount FS if the mount point is not specified in fstab
There is a special case when this can be a problem:
if during undeployment `absent` removes entry from `fstab` then tries to
unmount the share but fails for some reason. The next time undeployment
runs `mount==absent` will do nothing and the next task (that tries to
delete the local nonvolatile directory) will reproducibly fail with
permission denied.

ICSHWI-9566 Move RequireMountsFor to override.conf

See merge request !94

It did not work in the template 🤷
Also added a separate scenario to test that the systemd service
* tries to mount required NFS shares
* is not started if any of the required NFS shares cannot be mounted

ICSHWI-8931: Restart IOC if internal metadata changed

See merge request !93
