CLI: Config issues with pull

[josephjclark]

I've been doing some testing with openfn pull and seeing some issues

• Env vars are not loaded into the command
• Can't specify endpoint, apikey through CLI args
• I can't work out how to set the path to pull to (why can't I openfn pull <id> /repo/openfn/projects/my-project)
• Paths in config.json seem to be relative to the CLI's working dir, not the config.json itself. I suspect deploy is the same.

Basically the first pull experience seems way too complex

This is sort of resolved by #714. I'm going to close the issue for now - maybe we'll look at the other bits later.
