Add faulty file system for io failure injection

Add faulty file system to allow us to inject failure for low-level file operations in unit and fuzzer test.
It is implemented under velox filesystem. It is wrapper on top of the real file system, it either inject
errors or delegate the file operations to the underlying file system. We extend TempDirectoryPath or
TempFilePath to allow user to specify whether enable fault injection or not in test. If it does, it returns
the file or directory path with faulty file system scheme prefix (faulty:). This allows the velox file system
to open the file through faulty file system and by removing the faulty fs scheme prefix, it can delegate
the file operation to the corresponding underlying file system.

We support three kinds of file fault injections: (1) error injection which throws for a set (or all) file operation
types; (2) delay injection for a set (or all) file operation types; (3) custom injection with user provided fault
injection hook. We define the base structure FaultFileOperation to capture the file fault injection parameters
and each file api will extend with its own operation type.

This PR only supports fault injection for read file operations. Next we will extend to other file operation types
as well as fs operation types.
