#
# rpl_switch_stm_row_mixed tests covers
#
#   - switching explicitly between STATEMENT, ROW, and MIXED binlog format
#     showing when it is possible and when not. 
#   - switching from MIXED to RBR implicitly listing all use cases,
#     e.g a query invokes UUID(), thereafter to serve as the definition
#     of MIXED binlog format
#   - correctness of execution
