tlog_id specifes the active shard and is kept for backwards compatibility.
To avoid replicating information, the shard config file is used only to
specify inactive shards and must be used in conjunction with a tlog_id flag.
Together, these build the logRanges type in the sharding module.

* Update loginfo to return info about inactive shards

This also updates `rekor-cli` to verify inactive shards if they exist. It also updates the sharding integration test to run loginfo and store state based on TreeID if available.

We will need this so we can get proofs for inactive shards. This will be used by `loginfo`.

When printing the TreeID with rekor-cli loginfo, if the output is parsed through jq
then the TreeID gets rounded down as an int because it is bigger than JSON allows Numbers to be.

This is how jq works and is mentioned in the FAQ: https://github.com/stedolan/jq/wiki/FAQ#numbers



Switching this to a string will preserve the actual Tree ID.

* Add helpers and refactor sharding package

- Adds a function to get a TreeID from an ID string
- Adds testing for the above
- Consolidates validation logic for UUID, TreeID, EntryID
- Removes code that attempts to use ActiveIndex() in the sharding
  package, as this is not accessible due to import cycles
- Other small cleanup and typo fixes

This is changing as part of the general trillian signature changes.
The trust model is still client -> database, our server trusts our
database so we can pass signed messages on directly to users without
double verification.

This patch removes the /api/v1/log/entries/{uuid}/proof endpoint. If you
have the UUID (aka the leaf Merkle hash), you likely want proof that the
content represented by that hash is included in the log. There's no need
for a separate /proof endpoint to deliver the same content.

This commit also ensures that the getLogEntryByIndex and
getLogEntryByUUID endpoints return an inclusion proof as part of their
response content. The search endpoint also now returns the inclusion
proof of all entries returned from the query.

With this patch, Rekor no longer uses the deprecated `GetLeavesByHash`
Trillian API.

Fixes #229

Currently we return a 500 error if a consistency proof is requested for
a size that exceeds the current state of the log. This change causes a
400 "Bad Request" error with a more descriptive error message to be
returned.

After #77, we have one global GRPC channel for the entire process. This
change causes each GRPC call to be made on the incoming HTTP request's
context such that if an HTTP client cancels prematurely, we will handle
the GRPC cleanup appropriately.
