[ZEPPELIN-3264] Notebook Snapshot feature.
### What is this PR for?
Currently, a user can share the notebook with other users. There is a usage
pattern where data analyst creates notebook report and then share with other
stakeholders. Meanwhile, they would like to update/change the report and
re-publish the results.
We need a shareable url like,
/notebook/{**Notebook ID**}/view/{**Snapshot Name**}
which can be shared to other users and can be updated with a logical
sharable report.
