ESV Secret Store Exports/Imports and Additional Secret Store Mapping Functions

[phalestrivir]

This PR does two things:

1. It changes how existing secret store functions work to allow for doing ESV secret store exports/imports within AIC, since at the time when I originally implemented these I didn't know there was a secret store that was modifiable within AIC.
2. It adds additional functions for modifications to the mappings specific to a secret store, this way we can add additional commands to the CLI for these (this is already done in this Frodo CLI PR)
