contractcourt: offer outgoing htlc one block earlier before its expiry

We need to offer the outgoing htlc one block earlier to make sure when
the expiry height hits, the sweeper will not miss sweeping it in the
same block. This also means the outgoing contest resolver now only does
one thing - watch for preimage spend till height expiry-1, which can
easily be moved into the timeout resolver instead in the future.

// Package labels contains labels used to label transactions broadcast by lnd.
// These labels are used across packages, so they are declared in a separate
// package to avoid dependency issues.
//
// Labels for transactions broadcast by lnd have two set fields followed by an
// optional set labelled data values, all separated by colons.
//   - Label version: an integer that indicates the version lnd used
//   - Label type: the type of transaction we are labelling
//   - {field name}-{value}: a named field followed by its value, these items are
//     optional, and there may be more than field present.
//
// For version 0 we have the following optional data fields defined:
//   - shortchanid: the short channel ID that a transaction is associated with,
//     with its value set to the uint64 short channel id.
