Support variable stack names

[tgass]

Given:
In my senza definition file, the StackName is defined using an Arguments-variable:

StackName: "wps{{Arguments.StackNamePostfix}}"

Unfortunately, lizzy doesn't resolve the argument. I get the following error:

Requesting new stack.. EXCEPTION OCCURRED: 404 Client Error: NOT FOUND for url: https://lizzy-zprice-test.zprice-test.zalan.do/api/stacks

[AGENT] Stack not found: wps{{Arguments.StackNamePostfix}}-74ee2ddxb35

FAILURE: Build failed with an exception.

I'd like to see that lizzy can handle variables in stack names.

PS
I suppose this can be handle in the client.

@tgass Of course, it can be implemented on either side of lizzy. But for me it looks, that this is a feature of lizzy-agent, not client.

We also needed this feature. Had to implement our own config rendering step before using lizzy in the pipeline.
