feat: Add the managed disaster recovery API(https://cloud.google.com/…

…bigquery/docs/managed-disaster-recovery) (#7869)

feat: Add a new field `is_flat_rate` to `.google.cloud.bigquery.reservation.v1.CapacityCommitment` to distinguish between flat rate and edition commitments
docs: Clarify that `Autoscale.current_slots` in message `.google.cloud.bigquery.reservation.v1.Reservation` can temporarily be larger than `Autoscale.max_slots` if users reduce `Autoscale.max_slots`
docs: Update comment for `slot_capacity` in message `.google.cloud.bigquery.reservation.v1.Reservation` to provide more clarity about reservation baselines, committed slots and autoscaler SKU charges when the baseline exceeds committed slots
docs: Update comments for `commitment_start_time` and `commitment_end_time` in message `.google.cloud.bigquery.reservation.v1.CapacityCommitment` to provide details on how these values are affected by commitment renewal
