Improve logging around new schema registration #172
Description
We do log a line saying that schema is being registered since it was not registered already:
Registering the schema for tablet 05dcfeff42494346b2149d772b973158 since it was not registered already
The above line works fine for all the cases except for colocated tables. Say there are 3 colocated tables, then we will get the same log line 3 times which is a little confusing from the UX point of view. In that case, this log can be improved to also add the table name if possible so that it is clear for which tablet-table pair we are registering the schema for.
