Create tables and schemas with lower case name only if the flag is set.
During operations, convert to lowercase in plugin. Byt the time a query gets to ExeMgr, DDLProc etc., everything must be lower case if the flag is set, and undisturbed if not.
when a non-existing table is dropped.
This patch accomodates the changes made to server 10.5 as part
of MDEV-11412, where the server now tries to drop the table from
all storage engines when a .frm table does not exist.
We were earlier retuning a warning to the client and setting the
return code to 0. We now instead return ER_NO_SUCH_TABLE_IN_ENGINE
error code to the server if the table does not exist in
ColumnStore.
this is executed when ha_columnstore is loaded, at dlopen time

Crashes - because a missing config file is a crashing offence,
but it's an issue for another day
This patch fixes:
MCOL-3557 - Row Based Replication events to ColumnStore tables will no
longer cause MariaDB to crash, it will error instead.
MCOL-3556 - Remove the Columnstore.xml variable to turn on ColumnStore
tables applying replication events and instead make it a system variable
that can be set in my.cnf called "columnstore_replication_slave". This
allows it to be set per-UM.
