Using the coiled client with newer versions of ddtrace causes exceptions

[samantha-earthmover]

If ddtrace is installed and tracing is enabled, there's some code that blows up in the coiled client while sending api requests

ddtrace=3.14.3

builtins.typeerror: HTTPPropagator.inject() got an unexpected keyword argument 'span_context'

A fix would be nice, but in lieu of that if one of you could grab me the version of ddtrace that y'all are using so I can downgrade us to that, trying to figure out when they renamed it is a pain.

We're on 2.10.6 in the control plane

Workaround in the meantime for anyone who stumbles on this and does not want to downgrade.

import coiled.context
coiled.context.DDTRACE = False
