DID Comm V2 - Incorrect controller data models

[sudeshrshetty]

Due to recent updates in normalizing command controllers for DIDComm V1 & V2 support, command controller data models are not actually matching with the actual parameters a command controller is expecting.

• https://github.com/hyperledger/aries-framework-go/blob/main/pkg/controller/command/issuecredential/models.go#L76
• there may be few more

For example: even though a command controller function says it accepts GenericInvitation it actually accepts outofband.Invitation V1 or outofband.Invitation V2. Hard for clients to find out what to send as request.

also, wallet users has to convert aries out of band invitation manually to generic invitation in order to use wallet. Need better design.
