The repair-peers cache is reset each time repair service loop runs,
and so computed repeatedly for the same slots:
https://github.com/solana-labs/solana/blob/d2b07dca9/core/src/repair_service.rs#L275
This commit uses an LRU cache to persists repair-peers for each slot.
In addition to LRU eviction rules, in order to avoid re-using outdated
data, each entry also has 10 seconds TTL.

Broadcast stage and retransmit stage should arrange nodes on turbine
broadcast tree in exactly same order. Additionally any changes to this
ordering (e.g. updating how unstaked nodes are handled) requires feature
gating to keep the cluster in sync.
Current implementation is scattered out over several public methods and
exposes too much of implementation details (e.g. usize indices into
peers vector) which makes code changes and checking for feature
activations more difficult.
This commit encapsulates turbine peer computations into a new struct,
and only exposes two public methods, get_broadcast_peer and
get_retransmit_peers, for call-sites.

* Report 404 instead of 502 when a snapshot file is not found
This provides the client with more useful information about why their
request failed
(cherry picked from commit 40d696fcbc)
* As a last resort try to download an uncompressed snapshot
`solana-test-validator` creates uncompressed snapshots and it can be
useful to attach another validator to a `solana-test-validator` cluster
from time to time

I wanted to use this sysvar to get a recent block hash, but I didn't
know whether the first or the last entry contains the most recent block
hash.
By calling it for mainnet, printing the results, and comparing that to
the recent blocks on solanabeach.io/blocks, I discovered that the
entries are ordered from most recent to least recent. Document this to
save future readers the trouble.

* Zelcore wallet support for SOL/SPLs info added
I have added a quick infodump about Zelcore wallet supporting various features of the Solana ecosystem. I looked at previous commits and it seemed adding to the top of the file was the norm, but please feel free to move around if needed.
* Zelcore wallet info moved to bottom of file.
