Python: Bug: Process Framework KernelProcessStep.on_activate is never called

[Druid-of-Luhn]

Describe the bug

The abstract class KernelProcessStep has an on_activate method, which one would assume is called when the step is activated, but the method is never called.

To Reproduce

Steps to reproduce the behavior:

1. Create a KernelProcessStep subclass that overrides the on_activate method,
2. Put the step into a process,
3. Run the process: the on_activate method is never called.

Expected behavior

The KernelProcessStep.on_activate method would be called when a step is activated, in both the local and Dapr runtimes. This would act as a form of zero-argument init method for when a step is activated.

Screenshots

Result of the code search showing that on_activate is never called.

@eavanvalkenburg - can you take a look?

@Druid-of-Luhn - thanks for reporting this!

@Druid-of-Luhn thanks for calling this out, turns out that was a leftover from a previous iteration, it was surpassed by the activate function that also sets up state, I have created a PR that removes it from both the KernelProcessStep and the sample.
