/**
* {@code VaultKeyResolver} is a {@link BiFunction} whose implementation of the {@link #apply(Object, Object)} method takes
* two {@link String}s representing the realm name and the key name (as used in {@code ${vault.key}} expressions) and returns
* another {@link String} representing the final constructed key that is to be used when obtaining secrets from the vault.
*
* Implementations essentially define the algorithm that is to be used to combine the realm and the key to create the name
* that represents an entry in the vault.
