* feat(joblist,runtime): this is the first part of the execution model that produces a workload that can be predicted for a given query.
- forces to UM join converter to use a value from a configuration
- replaces a constant used to control a number of outstanding requests with a value depends on column width
- modifies related Columnstore.xml values
* Minor fix in timeout for /notfound "endpoint" call.
- [fix] timeout to urlopen /notfound "endpoint" in mcs-savebrm and mcs-loadbrm
* chore(CMAPI): reduced a second Time Out asking MDB for a async replication status. The latency must be small b/c MDB Server to be requested is local.

This changeset enables quick (mariadb -q) mode when columnstore is
installed. Quick mode precludes client CLI program from storing too
much data in memory, preventing out of memory conditions.
* Fixes of bugs from ASAN warnings, part one
* MQC as static library, with nifty counter for global map and mutex
* Switch clang to 16
* link messageqcpp to execplan
Added logical transformation of the execplan::ParseTrees with the taking out the common factor in expression of the form "(A and B) or (A and C)" for the purposes of passing a TPCH 19 query.

[fix] oam/install_scripts/mcs-savebrm.py.in , now everytime using method to detect primary node
[fix] condition style in oam/install_scripts/mcs-loadbrm.py.in
[fix] bug in detecting primary.
[fix] minor bugs.
[add] not getting meta on secondaries if no cmapi available on primary node.
[fix] postinstall script to mask mariadb-columnstore service on multinode configurations.
Removed "requests" external python dependency to keep working with preinstalled python3.
Add fallback to detect primary if CMAPI is unreachable with hostname resolving.
Fix various minor python code styling.
f
by default), which when enabled, indiscriminately invalidates all
column extents and performs the actual DELETE only on the AUX
column. The trade-off with this approach would now be that the
first SELECT for certain query patterns (those containing a WHERE
predicate) after the DELETE operation will slow down as the
invalidated column extent would need to be scanned again to set
the min/max values.
* MCOL-4560 remove unused xml entries and code that references it.
There is reader code and variables for some of these settings, but nobody uses them.
EM and PP are most resource-hungry runtimes.
The merge enables to control their cummulative
resource consumption, thread allocation + enables
zero-copy data exchange b/w local EM and PP facilities.
* Fix clang warnings
* Remove vim tab guides
* initialize variables
* 'strncpy' output truncated before terminating nul copying as many bytes from a string as its length
* Fix ISO C++17 does not allow 'register' storage class specifier for outdated bison
* chars are unsigned on ARM, having if (ival < 0) always false
* chars are unsigned by default on ARM and comparison with -1 if always true
