Set run_as for analysis-projects based on if it's for "production"

The idea behind this is so that users can create AnPs for imported (non-production) datasets where builds will run as them rather than the standard apipe-builder.
This doesn't seem to play nice with the existing CLE hack [Genome::Config::AnalysisProject#L154](https://github.com/tmooney/genome/blob/customize_anp_run_as/lib/perl/Genome/Config/AnalysisProject.pm#L154).  This would override anything labeled `is_production` to run as `apipe-builder`.  So it seems `is_cle` and `is_production` are mutually exclusive though I feel like `is_cle` implies `is_production`.  However, if that's the case then `is_cle` needs to override the default `is_production` behavior.
