* PT-2160 - Fix tests for pt-online-schema-change
Re-enabled tests after MySQL bug #89441 fix in 8.0.14 and later
Updated t/pt-online-schema-change/samples/basic_no_fks_innodb.sql, so its unique index is NOT NULL
Added synchonizations when tests are waiting for too long due to slave catch up
Added innodb_directories option for t/pt-online-schema-change/pt-244.t
* PT-2160 - Fix tests for pt-online-schema-change
PT-2048 - pt-osc spans excessive connections to the replica when executing in the source
t/pt-online-schema-change/slave_lag.t was failing due to PT-2048. I added code that reuses already created connections when checks for slave in the wait loop. It fixes slave_lag.t too.
I also added that prints more detailed error when fails to connect to the replica.
* PT-2160 - Fix tests for pt-online-schema-change

Fixed search for HASH and BTREE keys broken by fix for PT-2123
Updated modules for pt-archiver
Fixed die message for sandbox/start-sandbox
Added global_grants table to list of exceptions for the ok function in lib/Sandbox.pm
Added wait_for_slaves to bugs.t, so changes on the source are copied to replica before pt-osc starts working
Updated PXC tests
Added wait_for_slaves to pt-1455.t
Fixed regular expression in pt-229.t, so it works with both 5.x and 8.0 versions
Added innodb_directories option for pt-244.t, so it does not fail on 8.0
Modified slave_lag.t, so it is more stable and slow enough, so pt-osc can print message about delayed replicas
* PT-2141 Fix tests for pt-archiver
Fixed tests t/pt-archiver/bulk_insert.t, t/pt-archiver/issue_1225.t, t/pt-archiver/issue_1229.t
Their failures were due to change of utf8 alias from utf8mb3 in MySQL 5.7 to utf8mb4 in MySQL 8.0.
And also due to character set match check between connection ad source table.
* PT-2141 Fix tests for pt-archiver
Removed test for PT-1898, because it was broken from the beginning:
- it called pt-online-schema-change instead of pt-archiver
- it announced it will run 6 tests while was running only 2
- the test case itself did not test the issue, described in PT-1898

the word 'Generated'.
* PMM-1914 Updated TableParser in all programs
* PT-1914 Updated changelog
* PT-1914 Added test
Since now NibbleIterator can fallback to nibble (from one chunk) pt-osc
can nibble tables even if due to unacurate stats, it choses one nible as
the initial nibbling method.
