Felföldi Zsolt	b4a2681120	les, les/lespay: implement new server pool (#20758) ... This PR reimplements the light client server pool. It is also a first step to move certain logic into a new lespay package. This package will contain the implementation of the lespay token sale functions, the token buying and selling logic and other components related to peer selection/prioritization and service quality evaluation. Over the long term this package will be reusable for incentivizing future protocols. Since the LES peer logic is now based on enode.Iterator, it can now use DNS-based fallback discovery to find servers.

gary rong	f78ffc0545	les: create utilities as common package (#20509) ... * les: move execqueue into utilities package execqueue is a util for executing queued functions in a serial order which is used by both les server and les client. Move it to common package. * les: move randselect to utilities package weighted_random_selector is a helpful tool for randomly select items maintained in a set but based on the item weight. It's used anywhere is LES package, mainly by les client but will be used in les server with very high chance. So move it into a common package as the second step for les separation. * les: rename to utils	5 years ago
