DeployedFlow.from_argo_workflows is incompatible with hyphen param names and apostrophes in param help

[chrschorn]

When using DeployedFlow.from_argo_workflows, some valid param configurations lead to errors. This seems to be because a "fake" flow file is constructed that will have invalid Python syntax:

• param names with hyphens (e.g. dry-run) become dry-run = Parameter(...) which is invalid Python syntax
• param help/descriptions with ' in them become dry_run = Parameter('dry_run', type=bool, help='Dry run, don't upload any results', required=False) which is also invalid (string is ended early by don't)
