    Description

      The command path on mongod places the command's extracted readConcern args on an operation context decoration. This allows the readConcern to be accessed wherever the operation context is passed.

      For global point in time reads, we'll need a way to check if a command is running with snapshot readConcern on mongos, which we can do by setting this decoration when mongos first parses readConcern in strategy.cpp.
