Ready for review! Notable:
Tests are good and present multiple interesting cases (from/to utf8, from/to latin1, latin1-to-latin2, nullable, ...) |

Description
Supporting non UTF8 character sets in OnlineDDL/VReplication:
latin1tolatin2)Implementation:
VReplication's filter->rule now has a new field,
CharsetConversion, which tells Vreplication:VReplication plan will programmatically convert binlog text values according to the above.
VCopier adds a
convert(<column> using utf8mb4)to any textual column where charset/collation has changedVStreamer identifies the
convert()function and similarly runs aconvert(... using utf8mb4)on same column as VCopier hinted, so that we convert the columns on the source sideRelated Issue(s)

Notes
