piwww: Add RFP process to testrun command.

[amass01]

This diff adds the RFP process to piwww testrun command.

It covers the following commands:

• Create RFP
• Make RFP public
• Authorize it for vote
• Start vote on RFP
• Cast RFP votes
• Wait until RFP votes is done
• Create 4 RFP submissions:
  • 1 Unreviewed
  • 2 Public
  • 1 Abandoned
• Start runoff vote
• Cast first public submission votes
• Wait until runoff vote is done
• Ensure first submission was approved.

And the following failures/edge cases as @lukebp suggested:

• Attempting to submit an RFP submission before the RFP vote has been approved.
• Submit an RFP, have the vote fail, attempt to submit an RFP submission to failed rfp.
• Attempting to vote on the abandoned proposal submission during runoff vote.

Closes #1190

Can we test some of the failure and edge cases as well. Things like:

• Attempting to submit an rfp submission before the rfp vote has been approved.
• Submit an rfp, have the vote fail, attempt to submit an rfp submission to failed rfp.
• Attempting to vote on the abandoned proposal submission during runoff vote.

We don't need to get too in-depth with it, that's what the unit tests are for, but testing some of the basic stuff would be a helpful sanity check.

[amass01]

That's a good idea, will add all these cases.

@lukebp Added all suggested test cases.
