program management like supervisor

example configuration file:

loglevel = "trace"

[[program]]
name = "short"
command = "date"
processes = 1
start_policy = "auto"
valid_exit_codes = [0]
stdout = "./test.log"
stdout_truncate = false

[[program]]
name = "long"
command = "sleep"
args = ["15"]

[[program]]
name = "never ending"
command = "yes"

school bonus
