WithTxRetries is a functional option that allows us to specify the number of times a transaction should be retried if it fails with a repeatable error.

WithTxRetryDelay is a functional option that allows us to specify the delay to wait before a transaction is retried.

DefaultNumTxRetries is the default number of times we'll retry a transaction if it fails with an error that permits transaction repetition.

TransactionExecutor is a generic struct that abstracts away from the type of query a type needs to run under a database transaction, and also the set of options for that transaction.

BatchedQuerier is a generic interface that allows callers to create a new database transaction based on an abstract type that implements the TxOptions interface.
