PT-2156 Fix tests for lib, part2 (#650)

* PT-2156 - Fix tests for lib

Fixed tests, broken by putting fix for PT-1554 into the library code, mostly by updating checksums.
Added AutoCommit option for test lib/QueryReview.t
Reset SQL mode to empty to allow TableChunker to work with invalid and zero dates

* PT-2156 - Fix tests for lib

Adjusted t/lib/SchemaIterator.t to work with version 8.0

* PT-2156 - Fix tests for lib

Adjusted b/t/lib/Processlist.t, so it reflects fix for PT-981

* PT-2156 - Fix tests for lib

Adjusted t/lib/HTTP/Micro.t, so it works with different order of parameters, returned at v.percona.com/
Adjusted test for empty files in t/lib/bash/collect.t
Disabled mysqladmin debug test in t/lib/bash/collect.t, because of PT-2242

* PT-2156 - Fix tests for lib

Added LC_NUMERRIC=POSIX into t/lib/bash/report_system_info.sh, so reports in tests are not environment-dependent
Updated expected results in t/lib/bash/report_system_info.sh, so they reflect new information, collected by pt-summary

* PT-2156 - Fix tests for lib

- Improved fix for PT-76, so it handles inline comments
- Added test case for PT-76
- Improved fix for PT-1720, so it ignores unrecognizable option only if it comes from the toolkit-wide files and still errors out if wrong option was passed via command line or the tool-specific option file.

* PT-2156 - Fix tests for lib

- Improved fix for PT-2102, so it finds running instance configuration file using PID and also does not break t/lib/bash/report_mysql_info.t test
- Removed unnecessary copy-paste from t/pt-mysql-summary/pt-2102.t test
- Adjusted number of collected files in t/lib/bash/collect_mysql_info.sh

* PT-2156 - Fix tests for lib

- Fix for PT-1543 and MyRocks collection were originally put only into lib/bash/report_mysql_info.shthat broke the logic of collecting data first, then formatting report from this data. This, in its turn, broke test t/lib/bash/report_mysql_info.sh/t/lib/bash/report_mysql_info.t, because CMD_MYSQL is not defined in this library. I rewrote these fixes, so they follow original logic of the tool (pt-mysql-summary)
- Added tests for keyring plugin, encrypted tables, and MyRocks for t/lib/bash/report_mysql_info.sh and t/pt-mysql-summary/pt-mysql-summary_encryption.t

* PT-2156 - Fix tests for lib

- Added FLUSH TABLES to t/lib/bash/collect.sh, so it does not fail opentables tests if run when more than 1000 tables open in the sandbox environment
- Changed number of expected sample files to reflect keyring colletion file

* PT-2156 - Fix tests for lib

- Added skip to some tests in lib that file when run with PXC, because not supported to work with PXC
- Adjusted configuration files for PXC, so they allow LOAD DATA/SELECT INTO OUTFILE commands
- Adjusted data samples, so they do not depend on auto increment values
- Fixed lib tests, failing with PXC

* PT-2156 - Fix tests for lib

Updated tests for pt-online-schema-change, so they work with PXC and skipped if designed for semi-synchronous replication setup

* PT-2156 - Fix tests for lib

- Added cluster-specific samples for t/lib/SchemaIterator.t
- Removed extra debugging print from t/pt-table-checksum/pt-1728.t
