Consistent caching strategy in QRE

[msoeken]

Is your feature request related to a problem? Please describe.
We need a consistent caching strategy in QRE as caching can take place in many different places:

• Resource estimation task (caching the results of estimate calls)
• Application models (caching the traces for application models, e.g., Q#, cirq)
• ISA Transforms (caching the ISAs from expensive ISA transforms, e.g., round-based factories)

Describe the solution you'd like

• Consistent parameter names and enablement of caching
• Configure the caching directory and caching state via some init call
