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

2f80c9d424 Used the source column definition to fetch and convert insert values 
When processing binlog insert statements, we want to use `sharedColumns`
to decide which values to fetch and convert from the insert DML event.

We only want to  `mappedShareColumns` to define the column names in the
`replace into ...` statement.

- `Column` type supports `convertArg()`: converting value of argument according to column data type
- DB URI attempts `utf8mb4,utf8,latin1` charsets in that order (first one to be recognized wins)
- Local tests filter by pattern
- Local tests append table schema on failure
- Local tests do not have postpone flag file
- Added character set local tests: `utf8`, `utf8mb4`, `latin1`

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
