allowing users to change parameters when exporting soopervisor

[edublancas]

A user is currently editing the generated Argo YAML spec to switch pipeline parameters (i.e., adding --env-param value) because the only way to change parameters currently is by switching the env.yaml but this implies re-building the docker image.

I think we have to replicate this behavior and study what the best solution is. On the one hand, I think if the only changed file in the project is the env.yaml, then, re-building and uploading the docker image will be fast but is still adding some overhead.

Alternatively, we can incorporate the --env parameter value feature in the CLI so it behaves more like the Ploomber CLI:

soopervisor export name --env--param value
