KUDU-2124. Don't hold session lock while initializing a TabletCopySession This patch replaces the interior mutex in TabletCopySourceSession with a dynamic once, so that initialization can happen concurrently. This allows initialization to happen outside of the critical section in the tablet copy service. Implemented a regression test that injects latency into BeginTabletCopySession() calls.
