Enum to varchar (#963)
* v1.1.0

* WIP: copying AUTO_INCREMENT value to ghost table
Initial commit: towards setting up a test suite

Signed-off-by: Shlomi Noach <2607934+shlomi-noach@users.noreply.github.com>

* greping for 'expect_table_structure' content

* Adding simple test for 'expect_table_structure' scenario

* adding tests for AUTO_INCREMENT value after row deletes. Should initially fail

* clear event beforehand

* parsing AUTO_INCREMENT from alter query, reading AUTO_INCREMENT from original table, applying AUTO_INCREMENT value onto ghost table if applicable and user has not specified AUTO_INCREMENT in alter statement

* support GetUint64

791d963ea0 Character set recognition and manipulation
- Identifying textual characters sets; converting into specific type when applying dml events
- Refactored `ColumnsList`: introducing `Column` type
- Refactored `unsigned` handling, as part of `Column`
- `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`

eeffa701d6 - Added ok-to-drop-table flag
- Added `switch-to-rbr` flag; applying binlog format change if needed
- Using dedicated db instance for locking & renaming on applier (must be used from within same connection)
- Heartbeat now uses `time.RFC3339Nano`
- Swap tables works! Caveat: short table outage
- `--test-on-replica` works!
- retries: using `panicAbort`: from any goroutine, regardless of context, it is possible to terminate the operation
- Reintroduced changelog events listener on streamer. This is the correct implementation.

04525887f3 - Throttling-check is now an async routine running once per second
- Throttling variables protected by mutex
- Added `--throttle-additional-flag-file`: `operation pauses when this file exists; hint: keep default, use for throttling multiple gh-osc operations`
- ColumnList is not a `struct` which contains ordinal mapping
- More implicit write changelog + audit changelog
- builder now builds `DELETE` and `INSERT` queries from data it will eventually get from DML event
- Sanity check for binlog_row_image
- Restarting replication to be sure binlog settings apply
- Prepare for accepting `SIGHUP` (reloading configuration)

a1a34b8150 ongoing development:
- accepts --max-load
- accepts multiple conditions in --max-load
- throttle includes reason
- chunk-size sanity check
- change log state writes both in appending (history) mode and in replacing (current) mode
- more atomic checks
- inspecting ghost table columns, unique key
- comparing unique keys between tables; sanity
- intersecting columns between tables
- prettify status
- refactored throttle() and retries()

0e7b23e6fe - Creating an populating Changelog table
- Using heartbeat
- Throttling works based on heartbeat
- Refactored binlog_reader stuff. Now streaming events (into golang channel, which makes for nice buffering and throttling)
- Binlog table listeners work
- More Migrator logic; existing logic for waiting on `state` events (e.g. `TablesCreatedState`)

4dd5a93ed7 - More work on go-mysql reader: now properly notes binlog coordinates as it makes progress
- Properly creating multiple BinlogEntry-ies when reading multi statement binlog event (Still todo: transactions)
