Summary: Now we store a revision number of a Shadow Tree that leads to a transaction for which the concrete instance of MountingTelemetry corresponds. This is useful to understand how many actual transactions were skipped during a mounting phase (a mounting transaction does not directly correspond to a commit operation). Changelog: [Internal] Fabric-specific internal change. Reviewed By: mdvacca Differential Revision: D23364663 fbshipit-source-id: 32b86bcdfc1ae97d8fff3b97a8615cc5a5b4d4a9
