Previously we could get a developer's shell into a bad state where a value of a config variable from a previous impala-config.sh version would override the value from the new impala-config.sh version. This change adds a new mechanism to override settings locally by adding settings to impala-config-local.sh. This alternative approach is more robust, because the config variables will be reset to the intended values when impala-config.sh is re-sourced. impala-config-branch.sh can also be used to override settings in a version-controlled way, e.g. to support having different settings for different branches. I did not convert all variables to use this approach, since many people and Jenkins jobs depend on setting these variables from the environment. The remaining "sticky" variables are ones where default values should not change frequently, e.g. source directory locations and build settings.
