[Discuss][DSIP] Support load binlog from MySQL directly without relying other service

[??]

As issue 
#8025(https://github.com/apache/incubator-doris/issues/8025) mentioned, 
the current binlog load is relying on Canal service. We can integrate the 
binlog aquire and parse function into Doris, so that user can be more 
convinience to use it.Please determine the final DSIP number for it.
