Support multiple QF rounds

[laurenluz]

In the future we may want to run multiple QF rounds simultaneously. For example - a climate round, DEI round, homelessness round etc.

We'd like to make it possible to have multiple active QF rounds, with different projects part of them.

@laurenluz do we need to update admin panel with relevant info : @mohammadranjbarz needs the confirmation

[jainkrati]

@CarlosQ96 can take this up and @mohammadranjbarz can guide / resolve doubts if needed.

spec is here for review, but tbh we might not want to prioritize all these issues right away. would love feedback from @mohammadranjbarz or @CarlosQ96: https://www.notion.so/giveth/Scaling-Quadratic-Funding-Spec-35e983483c5f4a53aa8da32c885955d1
