Add a couple of utility functions to the baseline test framework

Adds a function for setting the baseline Project name, which selects
the top level server directory and hence config settings.

Also adds a function that lets the client override the server config
setting for the project image keys (ItemPathKeys). This is the list of
properties that will be used to determine which clients are "the
same", i.e. which baseline to compare against. Overriding that is
handy since it allows experimentation and customization of clients
without involving changes in the project config on the baseline
server.

Pick-to: 6.3 6.2
