Bug Description

i was trying to use juju run to debug current settings for a subordinate unit ala

$ juju run --unit=agent/0 "relation-ids ceilometer-service"
ERROR agent/0 is not a principal unit

If we're being explicit about which unit we want to target.. i say just let the user do it.. --all can/should nanny filter subordinates, but if a user is specifically interested in running something on a subordinate i don't see the reason not to let them.

ie. i can juju ssh/scp into a subordinate unit without issue.. i don't see why run is being restricted.

Workaround:

"juju ssh service/0" gets me into the machine.
"juju-run service/0 ..." then seems to work.

On 1.20.7.

Python workaround:

import subprocess

def remote_run(unit, command):
    subprocess.check_call(['juju', 'ssh', unit] + command)

def remote_run_run(unit1, unit2, command):
    remote_run(unit1, ['juju-run', unit2, "'%s'" % command])

Then I can call, for example:

    remote_run_run('main-service/0', 'subordinate-service/0', '...')
