MaybeBeginTx is a helper function that can be used to initiate a transaction if the supplied storage implements the `Transactional` interface.

MaybeCommitTx is a helper function that can be used to commit a transaction if the supplied storage implements the `Transactional` interface.

MaybeRollbackTx is a helper function that can be used to rollback a transaction if the supplied storage implements the `Transactional` interface.

A storage provider that has support for transactions should implement this interface to ensure atomicity for certain flows that require transactional semantics.
