Remove deprecated methods & properties

[florian-h05]

• [rules] Remove deprecated state and receivedTrigger event object properties.
• [cache] Remove deprecated default cache (users should either use private or shared cache).
• [actions] Remove createTimerWithArgument (users should use createTimer or setTimeout instead, createTimerWithArgument is not even thread-safe).

All these have been marked as deprecated at least since openHAB 3.4, which was released end of 2022, which means users have had enough time to adjust their code.

@rkoshak FYI. I have checked openhab-rules-tools, only usage of deprecated methods I could find was in open_reminder.yaml and debounce.yaml. However both of these are only published for openHAB 3.x on the marketplace, therefore this should be fine.

I want to make sure that those versions of the rule templates remain compatible with the version of the helper library that comes with the 3.4 add-on so I'll leave them as is.

I agree, plenty of time has passed. There shouldn't be any OH 4 users trying to use these.

so I'll leave them as is.

Sounds reasonable :+1:

I agree, plenty of time has passed.

And moving away from the deprecated methods was relatively easy and straighforward.

I am getting rid of the deprecated stuff now because with #331 there already is a breaking change for the next release, so I can now bundle all breaking changes into one release.
