Use of `CachingCommX` in `driver` review

[fmalatino]

Currently driver has dependencies on CachingCommX methods from ndsl. This needs review such that they can be initialized, but not configured by the driver

[FlorianDeconinck]

Specifically the CachingCommXConfig are held by the driver and probably should be lowered to ndsl.

Same reasoning might apply to a lot of the configs in the driver and as part of this task a full review should be conducted
