In this commit, we add strict zombie pruning as a config level param. This allow us to add the option for those that want a tighter graph, and not change the default composition of the channel graph for most users over night. In addition, we expand the test case slightly by testing that the self node won't be pruned, but also that if there's a node with only a single known stale edge, then both variants will prune that edge.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
