> Currently, when an "invalidate content" request is created via one of these 2 routes:
> - POST /api/$version/user/current/jobs (thru the API)
> - POST /job/external/new (thru the UI)
> regex_revalidate.config is written to the file system at the location dictated by the 'snapshot_dir' parameter:
> https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_ops/app/db/seeds.sql#L32
> In order to support a highly-available/redundant TO, we need to remove all dependencies on files written to the file system. 
> My suggestion is that we remove all calls to snapshot_regex_revalidate() which will stop regex_revalidate.config from being written to the file system.
> https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_ops/app/lib/MojoPlugins/Job.pm#L35
> After this is done. regex_revalidate.config can be retrieved like all other ATS config files using the following route: /genfiles/view/:host_name/regex_revalidate.config
> If this change is made, ORT would also have to change
