Pi/special cap

[Quantumplation]

Implements controls to configure the scheme specified in this governance proposal:

In particular, this adds:

• EligibleAssets, EligiblePairs, DisqualifiedAssets, and DisqualifiedPairs
  • These give more controls for flagging pools as eligible or disqualified, so that SUNDAE/ADA pools can be disqualified
  • Technically, only the last one is needed, but I added the others for symmetry and flexibility
• FixedEmissions
  • This map defines which pools receive a fixed, constant amount of tokens, as opposed to the normal delegation based weight
  • This will be used to give pool 08 a fixed 30% of the daily emissions
• EmissionCap
  • This property defines a fixed upper limit on how much any pool receiving delegation-based emissions can receive
  • For example, this will be set to 14% of the daily emissions, which would mean anything receiving more than that would have the surplus returned to the treasury

Ultimately, this exact implementation and the choice of settings will need to be ratified via another governance proposal, since the first one was underspecified, but I believe this fairly closely implements the behavior outlined in that proposal.
