MDEV-15919 lower_case_table_names does not behave as expected(nor...

 consistently) on Replication Slave

lower_case_table_names  0 -> 1 replication works, it's safe as long as
 mixed case names mapping to the lower case ones is one-to-one

+# BUG#37656
+#
+#  This test aims at checking whether lower_case_table_names=1 option works
+#  for database names and table names.
+#
+#  This test checks the following (when lower_case_table_names=1 is set on slave):
+#    (i) creating a database on upper case on master results in lower case
+#        database name on slave
+#   (ii) creating tables with upper case names on master results in lower case
+#        table names on slave
+#  (iii) loading data infile into capitalized table name on master replicates to
+#        lower case table name on slave
+#   (iv) Propagating changes from upper case table names on into correspondent
+#        lower case table names on slave works.
