feat(#5864): Added configuration for sizeLimit on empty-dirs in mount trait

[hernanDatgDev]

The default SizeLimit on mount trait empty-dir volumes is now configurable with the following syntax:
trait.mount. empty-dirs=myVolumeName:/container/path:sizeLimit

Where sizeLimit is a normal resource quantity e.g. 1Gi, 500Mi, etc.

I considered something similar to components where we add configurations after a "?" however since the empty-dir volume source only takes 2 configurations:
SizeLimit
Medium

I figured it would be easier to just continue the ":" separation syntax. Please let me know your thoughts on this approach

Release Note

NONE

I need to update the documentation for the syntax on the trait still unless you have any concerns with the approach and I should change it. @squakez

I think the parsing is getting too complicated and out of the original scope. Probably it makes sense that we have a separate section in the mount trait that takes care to parse and to add volumes coming from the empty-dir parameter independently by the rest. In that way we can treat them appropriately adding any possible future syntax change.

Beside that, it would be good to set a default value on resource when the user is not providing it (either 1GB or anything lower).

[hernanDatgDev]

Made the changes so that logic is contained mostly within the mount trait. Parsing is kept to a minimum and I'd just need to update the syntax documentation if the logic looks good @squakez

LGTM. Please add the doc changes and have a look at the lint failure.

@squakez I've run make generate to handle the documentation update but there are a lot of additional changes that result from this change, specifically to the CRD definitions. They updates do include my updated documentation though.

Any thoughts? I can always revert this commit.

[squakez]

I see you're using an old controller-gen version. You need to upgrade to a more recent one (likely 0.15.0) and redo the generation.

[squakez]

Hi @hernanDatgDev how this one is going? I am planning to release 2.5.0 for next week, so, we should have this ready by then to include in the release.

[hernanDatgDev]

@squakez I'm sorry about the delay. I will get this updated and ready as soon as I can.

[squakez]

Let's wait for the checks to run. For now, don't worry about the autogenerated documentation, we have a nightly task taking care to update. However, for the future, we need to take care of synchronizing the tooling automatically, so, I'm opening a separate issue to take care of that.

Please, fix and make lint locally to run the validation and see no more errors.

EDIT: I've just fixed it inline to speed up the merge.
