Allow additional properties

Closes #316

Hi @fabrice-toussaint, can you give us some more insight on the additional property that you would like to add and what it would be mapped to in your use case?

[fabrice-toussaint]

@jamiezieziula we are trying to implement Prefect using vcluster to spin up a temporary environment. We want to be able to enable / disable specific charts (depending on the temporary environment). All other services that we use (i.e. postgres) allow us to set an additional property (i.e. enabled) so that we can include / exclude them.

We also need the property to be enabled on the "highest" level, so I could exclude it from the "lower" levels.

For context this means that something like:

is great. But something like:

is still not permitted which makes sense for these use cases.

[fabrice-toussaint]

Yes exactly that would work perfectly for us

lgtm - appreciate you explaining your use case!
