Refractor LockRenewer and Enable Compatibility with MultiProcessor

[karenychen]

• Refractor NewLockRenewalHandler to NewRenewLockHandler. The refractor gets rid of the lockRenewer argument in the constructor and instead uses the settler passed down from the handler function.
• Deprecate NewLockRenewalHandler
• The refractor also enables compatibility with MultiProcessor. The lock renewal handler now will automatically take in the correct settler for each receiver in the MultiProcessor.
  • Added UT to verify compatibility.
