Description

The thermos DSL:

class Process(Struct):
  cmdline = Required(String)
  name    = Required(String)

  # This is currently unused but reserved for future use by Thermos.
  resources     = Resources

  # optionals
  max_failures  = Default(Integer, 1)      # maximum number of failed process runs
                                           # before process is failed.
  daemon        = Default(Boolean, False)
  ephemeral     = Default(Boolean, False)
  min_duration  = Default(Integer, 5)      # integer seconds
  final         = Default(Boolean, False)  # if this process should be a finalizing process
                                           # that should always be run after regular processes
  logger        = Default(Logger, Empty)

If we can add a new field:

environment = Default(Map(String, String), {})

It will make it much easier to add environment variables.

Right now the solution is to prefix environment variables to cmdline which can get janky and frustrating with the string interpolation.
