Emit Kuberentes Events on major KEDA events

[zroubalik]

KEDA controller should emit Kuberentes Events on major events. This is based on #479

Use-Cases

• New Trigger Authentication Created
• Deployment Scaled to Zero
• New Scaled Object Created
• Information on scaling action
• Information about new scaled object referencing existing trigger authentication
• ...

Just curious are these just logs or there is something else first class that you are thinking ?

[tomkerkhove]

These are events similar which you can process in other applications, for example to extend KEDA, create awareness around scaling patterns (ie post to Slack), react to certain things, etc.

Sorry my question was that what would be the implementation to emit these "events" - would we just need to add the right logs at various places in the code.

[tomkerkhove]

That is a good question, I don't know the answer to that or if it's possible.

[zroubalik]

@anirudhgarg yes, that should be the case, but need to doublecheck first.

[tomkerkhove]

This would be a major feature if you ask me!

Can we target 2.0 for this @zroubalik @ahmelsayed @jeffhollan @anirudhgarg ?
