[Arcanist] add a local (per working copy) config file

Browse source 
Summary:
This adds the concept of a local (i.e. working copy local) config file
to arc.  This config file has the highest precedence for config
settings that may come from any config file.  The config is stored in
.(git|hg|sv)/arc/config, and is read ahead of the project config by
getConfigFromAnySource().

Test Plan:
#Testing arc set-config and arc get-config

#testing getConfigFromAnySource by means of lint
