Consider replacing string parsing with ast

[VyasGuru]

inspect_without_import.py currently uses basic string parsing to get the functions from start_tasks.py
This might cause problems with indenting and formatting with small things like whitespaces.

I'd suggest using Python's ast to inspect the file, as this makes it more robust and not susceptible to the parsing errors previously mentioned.

If there isn't anyone working on this already, I'd be glad to give this a go. Waiting for a maintainer to review this.

Thanks for filing this! Looks like this could be another instance of tech debt

Seeing a proof of concept for how you think this might be done better could be interesting, but Im hesitant to suggest spending time on it since its more of a theoretical issue (rather than something that causes an actual problem with deployed augur instances)
