[c++ client] notes for timestamp-related methods
Added notes on anticipated changes on methods related to getting
and setting hybrid timestamps while performing READ_AT_SNAPSHOT
scan operations:
* KuduClient::GetLatestObservedTimestamp()
* KuduClient::SetLatestObservedTimestamp()
* KuduScanner::SetSnapshotRaw()
Some changes are anticipated there in the context of KUDU-611.
In short, the timestamp might be replaced with some opaque type
(e.g., a sequence of bytes).
Also, added code sample to provide an idea how to use value returned
by KuduClient::GetLatestObservedTimestamp() to set appropriate snapshot
timestamp via KuduScanner::SetSnapshotRaw().
This addresses the following JIRA issues:
KUDU-1661 Mark KuduClient::GetLatestObservedTimestamp()
as experimental
KUDU-1663 Clean-up in-code documentation for KuduScanner::ReadMode
and KuduClient::GetLatestObservedTimestamp
