feat: sealing: More SnapDeals config knobs

[magik6k]

Proposed Changes

This PR adds 2 new config fields which should make a few more usecases for SnapDeals much easier to use.

  # Prefer creating new sectors even if there are sectors Available for upgrading.
  # This setting combined with MaxUpgradingSectors set to a value higher than MaxSealingSectorsForDeals makes it
  # possible to use fast sector upgrades to handle high volumes of storage deals, while still using the simple sealing
  # flow when the volume of storage deals is lower.
  #
  # type: bool
  # env var: LOTUS_SEALING_PREFERNEWSECTORSFORDEALS
  PreferNewSectorsForDeals = false

  # Upper bound on how many sectors can be sealing+upgrading at the same time when upgrading CC sectors with deals (0 = MaxSealingSectorsForDeals)
  #
  # type: uint64
  # env var: LOTUS_SEALING_MAXUPGRADINGSECTORS
  MaxUpgradingSectors = 0
