A machine might want this information to determine if it should emit
an effect like `{append, NewCmd}` that can only be handled once a
cluster reaches an effective machine version.
With `current_term/1` (this change), `last_applied/1` and `effective_machine_version/1` from the parent commit, the aux API reflects essentially the same information as is passed as metadata to the `RaMachine:apply/3` callback (`ra_machine:command_meta_data()`).

A machine might want to know the effective machine version to determine if it should emit an effect like
{append, NewCmd}that can only be handled once a cluster reaches an effective machine version.This change also exposes the
current_termso that the callers of the ra_aux API have essentially the same metadata as is passed to theRaMachine:apply/3callback.
