[Brian Vazquez <brianvv@google.com>]

From: Manoj Vishwanathan <manojvishy@google.com>

Add more information related to the transaction like cookie, vc_op,
salt when transaction times out and include similar information
when transaction salt does not match.

Info output for transaction timeout:
-------------------
(op:5015 cookie:45fe vc_op:5015 salt:45 timeout:60000ms)
-------------------
