Add support for custom Meta-Data (aka properties) in Cloud Template

[kikmon]

What feature do you want to see added?

We need to set 'Meta-Data' properties when creating cloud machines, (--property option when doing a server create command)
It seems the current template options do not expose this option.

Could it be possible to add a list of properties passed to the server when it's created ? (simple list of key-value)

Hi,
we're looking for too the capability to setup meta-data on agent created for resource monitoring purpose.
I was supposed the sub menu "node properties" was used for but not, perhaps this menu should be the right location to add meta-data keys/values we can add on related template.

Thanks.

I created a small MR to add this functionality (first time for me)
@olivergondza could you have a look at it please ? Your guidance will be appreciated :)
Tests seems to have been broken for quite some time and need attention. Is someone already looking into this ?
I'm also getting some errors related to building to java11, which is normal, but even if I specify JDK 17 + 21 in the jenkinsfile, it's still trying to build on JDK11
