Change subject: KUDU-456 Implement AUTO_FLUSH_BACKGROUND flush mode
......................................................................

KUDU-456 Implement AUTO_FLUSH_BACKGROUND flush mode

Implemented AUTO_FLUSH_BACKGROUND for the Kudu C++ client library.
KuduSession objects use RPC messenger's thread pool to schedule
background flush tasks.  In AUTO_FLUSH_BACKGROUND mode,
the KuduSession::Apply() method blocks if total amount of data
for operations not pushed to server reaches the buffer size limit.
The limit on the buffer size can be set by the
KuduSession::SetMutationBufferSpace() method.

The background flusher checks whether at least one of the following two
conditions is satisfied to determine whether it's time to flush
the accumulated write operations:
  * the over-the-waterline criterion: check whether the total size of the
    freshly submitted (i.e. not-scheduled-for-flush) write operations
    is over the threshold.  The threshold can be set as a percentage
    of the total buffer size using the
    KuduSession::SetMutationBufferFlushWatermark() method.
  * the maximum wait time criterion: check whether the previous flush
    happened more than the maximum wait time ago.  The maximum wait time
    can be specified in milliseconds using the
    KuduSession::SetMutationBufferFlushInterva() method.

This change also addresses the following JIRA issue:
  KUDU-1376 KuduSession::SetMutationBufferSpace is not defined
