This API endpoint was failing when tablets were enabled
because of usage of get_vnode_effective_replication_map().
Moreover, it was providing an error message that was not
user-friendly.
This change extends the handler to properly service the incoming requests.
Furthermore, it introduces two new test cases that verify the behavior of
storage_service/range_to_endpoint_map API. It also adjusts the test case
of this endpoint for vnodes to succeed when tablets are enabled by default.
The new logic is as follows:
- when tablets are disabled then users may query endpoints
for a keyspace or for a given table in a keyspace
- when tablets are enabled then users have to provide
table name, because effective replication map is per-table
When user does not provide table name when tablets are enabled
for a given keyspace, then BAD_REQUEST is returned with a
meaningful error message.
