config.parse should take a file name
Current Behavior
Right now, config.parse() reads tilt_config.json from the current directory, and merges
that argument list with what you specified on the command-line.

Describe the Feature You Want
In monorepos, you often want multiple tiltfiles to share the same tilt_config.json.
config.parse() should have some way to change where it's pulling the arguments from.
Additional context The simplest solution would be to have something like:
config.parse('./path/to/shared/config.json')
to specify where to load the file from.
It would be good, to have this. Or at least control the configuration path via an environment variable, e.g. TILT_CONFIG_PATH=path/to/file.json. I'm looking for this as I want a different configuration for CI versus local developers.
