LND v0.17.4-beta: Bug Fix Release

The Lightning Network Daemon (LND) is a complete implementation of a Lightning Network node developed by Lightning Labs.

"This is a hot fix release that fixes multiple bugs: Channel open hanging until restart, a memory leak when using polling mode for bitcoind, sync getting lost for pruned nodes and the REST proxy not working when TLS certificate encryption is turned on."

What's new

Fix the removal of failed channels. When a pending channel opening was pruned from memory no more channels were able to be created nor accepted. This PR fixes this issue and enhances the test suite for this behavior.
Fix an issue that caused memory leak for users running lnd with bitcoind.rpcpolling=1 mode.
Fix an issue for pruned nodes where the chain sync got lost because fetching of already pruned blocks from our peers was not garbage collected when the request failed.
Let the REST proxy skip TLS verification when connecting to the gRPC server to prevent invalid cert use when the ephemeral cert (used with the --tlsencryptkey flag) expires.
Allow callers of ListSweeps to specify the start height.
