* Difficulty RFC: Revised based on spec fixes
Update the design based on the spec bugs in #1276, #1277, and

These changes make the difficulty filter into a context-free check,
so we remove it from this contextual validation RFC.

We have to clone the data to pass a fixed-length array to a function,
so we might as well sort that array to find the median, and avoid a
copy.
## Motivation
Prior to this PR we've been using `sled` as our database for storing persistent chain data on the disk between boots. We picked sled over rocksdb to minimize our c++ dependencies despite it being a less mature codebase. The theory was if it worked well enough we'd prefer to have a pure rust codebase, but if we ever ran into problems we knew we could easily swap it out with rocksdb.
Well, we ran into problems. Sled's memory usage was particularly high, and it seemed to be leaking memory. On top of all that, the performance for writes was pretty poor, causing us to become bottle-necked on sled instead of the network.
## Solution
This PR replaces `sled` with `rocksdb`. We've seen a 10x improvement in memory usage out of the box, no more leaking, and much better write performance. With this change writing chain data to disk is no longer a limiting factor in how quickly we can sync the chain.
The code in this pull request has:
- [x] Documentation Comments
- [x] Unit Tests and Property Tests
## Review
@hdevalence
Prior to this PR we realized that the RFC had been drafted with the assumption that chains would be ordered from best to worst in `NonFinalizedState`. This assumption was incorrect, since `BTreeSet` only ever orders values in ascending order. This discrepancy was noticed and fixed in the code, but there were still some inconsistencies that needed to be cleaned up.
This PR updates all the incorrect or confusing comments about chain ordering in the RFC and code.
The difficulty validation RFC will introduce a definition of
per-block difficulty. Make it clear that the state RFC
definition is cumulative difficulty.
## Motivation
The zebra-state service needs to be able to handle duplicate blocks.
## Solution
This implements changes already outlined by [The State
RFC](https://zebra.zfnd.org/dev/rfcs/0005-state-updates.html). We check for
successfully committed blocks first, since interacting with the queued blocks
struct at this point just complicates the implimentation. If the block has not
already been committed we then check if the block has already been queued, if
not we handle the block normally (normally here being the bit we already had
implemented).
## Documentation Changes
- [x] Update the state RFC to match the ways this fix departs from the design
- the main thing is that I switched the order of checking for duplicates
- [x] ~~Add newly added functions to the state rfc~~ Decided not to do this because they're minor getters that don't influence the rest of the design and aren't exposed as part of the API
- [x] Document newly added functions inline
## Testing

Binding grafana to localhost makes it inaccessible from the wider internet,
which is a secure default.
Since we run docker with host networking, docker containers have access to D-Bus and other
security-related services on localhost. So it's risky to also expose them to the wider internet.

* Move to RFC number 5
* rfc: add PR link to state update RFC
* rfc: change state RFC to store blocks by height.
The rationale for this change is described in the document: it means
that we write blocks only to one end of the Sled tree, and hopefully
helps us with spatial access patterns.
This should help alleviate a major cause of memory use in Zebra's
current WIP Sled structure, which is that:
- blocks are stored in random, sparse order (by hash) in the B-tree;
- the `Request::GetDepth` method opens the entire block store and
queries a random part of its block data to determine whether a hash is
present;
- if present, it deserializes the complete block data of both the given
block and the current tip block, to compute the difference in block
heights.
This access pattern forces a large amount of B-tree data to remain
resident, and could probably be avoided if we didn't do that.

This PR has one unfortunate change, which is that the README.md and
CONTRIBUTING.md files in the book are symlinks to files in the parent
directory. The motivation for this is to ensure that we don't maintain two
copies of the same data, and that the landing page of the website matches the
landing page of the Github repo, etc. However, I'm not sure whether these
symlinks will work correctly on Windows.
The alternatives are:
- Duplicate the contents of the files and expect that people will know to keep
them in sync;
- Use relative links `../../README.md` in the `SUMMARY.md`. This seemed like
it caused mdbook to dump the rendered files into the repository root rather
than keeping them in the `book` directory.
- Use a symlink (chosen option). This may not work on Windows but I think that
the worst outcome would be that the book would be unbuildable unless someone
used WSL or something. This seems like the least bad option.
