7fa5e405d4 avoid writing heartbeat when throttle commanded by user
when throttling on user command there really is no need for injecting heartbeat. The user commanded, therefore gh-ost complies and trusts the reasoning for throttling. What this will allow is complete quiet time. This, in turn, will allow such features as relocating via orchestrator/pseudo-gtid at time of throttling

15f4ddfd8a support for --critical-load-interval-millis
this optional flag gives --critical-load a second chance. When configured to positive value, meeting with critical-load spawns a timer. When this timer expires a second check for critical-load is made; if still met, gh-ost bails out.
By default the interval is zero, in which case gh-ost bails out immediately on meeting critical load.

1f65473e69 support for --discard-foreign-keys
This flag makes migration silently and happily discard any existing foreign keys on migrated table. This is useful for intentional dropping of foreign keys, as gh-ost does not otherwise have support for foreign key migration.
At some time in the future gh-ost may support foreign key migration, at which time this flag will be removed

2afb86b9e4 support for millisecond throttling
- `--max-lag-millis` is at least `100ms`
- `--heartbeat-interval-millis` introduced; defaults `500ms`, can range `100ms` - `1s`
- Control replicas lag calculated asynchronously to throttle test
  - aggressive when `max-lag-millis < 1000` and when `replication-lag-query` is given

a62f9e0754 Add --test-on-replica-manual-replication-control flag
This will wait indefinitely for the replication status to change.
This allows us to run test schema changes in RDS without needing
custom RDS commands in gh-ost.
