MDEV-26971 post-fix: fixes for SST scripts
1) Fixed a bug with incorrect calculation of the payload length
when using the --innodb-undo-directory option on the command
line (not in the .cnf file);
2) Fixed a bug with incorrect processing of progress=none in the
presence of *.qp-files;
3) Progress processing for *.qp-files has been made more logically
unified with the semantics of the adjust_progress function;
4) Added forgotten option "--maxdepth 1" when searching for
*.qp-files;
5) Eliminated "cosmetic" differences with the SST scripts in
previous versions, which otherwise will cause problems when
automatically migrating future changes;
6) Fixed a bug caused by automatic migration of the MDEV-27524.
Small fixes
Add new requirement for pv tool for debian and rpm
Fix one test result difference.

MDEV-26971: JSON file interface to wsrep node state.
Integration with status reporter in wsrep-lib.
Status reporter reports changes in wsrep state and logged errors/
warnings to a json file which then can be read and interpreted by
an external monitoring tool.
Rationale: until the server is fully initialized it is unaccessible
by client and the only source of information is an error log which
is not machine-friendly. Since wsrep node can spend a very long time
in initialization phase (state transfer), it may be a very long time
that automatic tools can't easily monitor its liveness and progression.
New variable: wsrep_status_file specifies the output file name.
If not set, no file is created and no reporting is done.
