FileLogger:Implement synchronous file logging
This commit implements synchronous safe file logging. Certain traces,
for example VPD write action, in the repo need to be logged into
specific files. FileLogger class facilitates this. Note: this
synchronous file logging implementation is not multi-thread safe.
