This removes auto-configuration of the snap.*.ethdisco.net DNS discovery tree.
Since measurements have shown that > 75% of nodes in all.*.ethdisco.net support
snap, we have decided to retire the dedicated index for snap and just use the eth
tree instead.
The dial iterators of eth and snap now use the same DNS tree in the default configuration,
so both iterators should use the same DNS discovery client instance. This ensures that
the record cache and rate limit are shared. Records will not be requested multiple times.
While testing the change, I noticed that duplicate DNS requests do happen even
when the client instance is shared. This is because the two iterators request the tree
root, link tree root, and first levels of the tree in lockstep. To avoid this problem, the
change also adds a singleflight.Group instance in the client. When one iterator
attempts to resolve an entry which is already being resolved, the singleflight object
waits for the existing resolve call to finish and returns the entry to both places.
This upgrades the cloudflare client dependency to v0.14.0. The new
version changes the API because all methods now require a context
parameter. This change also reduces the log level of the 'Skipping...'
message to debug, following a similar change in the AWS deployer.
This updates the DNS deployer to use AWS SDK v2. Migration is relatively
seamless, although there were two locations that required a slightly
different approach to achieve the same results. In particular, waiting for
DNS change propagation is very different with SDK v2.
This change also optimizes DNS updates by publishing all changes before
waiting for propagation.
This replaces the github.com/pborman/uuid dependency with
github.com/google/uuid because the former is only a wrapper for
the latter (since v1.0.0).

* accounts/scwallet: use go-ethereum crypto instead of go-ecdh
github.com/wsddn/go-ecdh is a wrapper package for ECDH functionality
with any elliptic curve.
Since 'generic' ECDH is not required in accounts/scwallet (the curve is
always secp256k1), we can just use the standard library functionality
and our own crypto libraries to perform ECDH and save a dependency.

golang-lru is now a go module, and the upgrade corrects a couple
of minor issues. In particular, the library could crash if you inserted
nil into an LRU cache.

This replaces the JavaScript interpreter used by the console with goja,
which is actively maintained and a lot faster than otto. Clef still uses otto
and eth/tracers still uses duktape, so we are currently dependent on three
different JS interpreters. We're looking to replace the remaining uses of otto
soon though.
* p2p/dnsdisc: add support for enode.Iterator
This changes the dnsdisc.Client API to support the enode.Iterator
interface.
* p2p/dnsdisc: rate-limit DNS requests
* p2p/dnsdisc: preserve linked trees across root updates
This improves the way links are handled when the link root changes.
Previously, sync would simply remove all links from the current tree and
garbage-collect all unreachable trees before syncing the new list of
links.
This behavior isn't great in certain cases: Consider a structure where
trees A, B, and C reference each other and D links to A. If D's link
root changed, the sync code would first remove trees A, B and C, only to
re-sync them later when the link to A was found again.
The fix for this problem is to track the current set of links in each
clientTree and removing old links only AFTER all links are synced.
