Description

This PR adds in TableName to the DiffReport struct. This is so when using a vtctl command with the json output, instead of getting output like

 {
"ProcessedRows": 0,
"MatchingRows": 0,
"MismatchedRows": 0,
"ExtraRowsSource": 0,
"ExtraRowsTarget": 0
}

We get:

 {
"ProcessedRows": 0,
"MatchingRows": 0,
"MismatchedRows": 0,
"ExtraRowsSource": 0,
"ExtraRowsTarget": 0,
"TableName": "t1"
}

This makes it easier to parse and also see what tables have diffs versus seeing what individual tables have diffs and not being able to see the overall information for the vdiff run for that table.
