## Motivation
This PR is motivated by the regression identified in https://github.com/ZcashFoundation/zebra/issues/1349. That PR notes that the metrics stopped working for most of the crates other than `zebrad`.
## Solution
This PR resolves the regression by deduplicating the `metrics` crate dependency. During a recent change we upgraded the metrics version in `zebrad` and a couple other of our crates, but we never updated the dependencies in `zebra-state`, `zebra-consensus`, or `zebra-network`. This caused the metrics macros to attempt to retrieve the current metrics exporter through the wrong function. We would install the metrics exporter in `0.13`, but then attempt to look it up through the `0.12` crate, which contains a different instance of the metrics exporter static variable which is unset. Doing this causes the metrics macros to return `None` for the current exporter after which they just silently give up.

## Follow Up Work
I noticed we have quite a few duplicate dependencies in our tree. We might be able to save some compilation time by auditing those and deduplicating them as much as possible.

Because the new version of the prometheus exporter launches its own
single-threaded runtime on a dedicated worker thread, there's no need
for the tokio and hyper versions it uses internally to align with the
versions used in other crates. So we don't need to use our fork with
tokio 0.3, and can just use the published alpha. Advancing to a later
alpha may fix the missing-metrics issues.
If the limit is less than the ideal, try to increase it to the ideal.
If that doesn't work, try to increase the limit as high as possible.
If the limit is still less than the minimum, panic.
As we approach our alpha release we've decided we want to plan ahead for the user bug reports we will eventually receive. One of the bigger issues we foresee is determining exactly what version of the software users are running, and particularly how easy it may or may not be for users to accidentally discard this information when reporting bugs.
To defend against this, we've decided to include the exact git sha for any given build in the compiled artifact. This information will then be re-exported as a span early in the application startup process, so that all logs and error messages should include the sha as their very first span. We've also added this sha as issue metadata for `color-eyre`'s github issue url auto generation feature, which should make sure that the sha is easily available in bug reports we receive, even in the absence of logs.

This commit changes the state system and database format to track the
provenance of UTXOs, in addition to the outputs themselves.
Specifically, it tracks the following additional metadata:
- the height at which the UTXO was created;
- whether or not the UTXO was created from a coinbase transaction or
not.
This metadata will allow us to:
- check the coinbase maturity consensus rule;
- check the coinbase inputs => no transparent outputs rule;
- implement lookup of transactions by utxo (using the height to find the
block and then scanning the block) for a future RPC mechanism.
Closes#1342
The UTXO query system assumes that a transaction will only request
information about UTXOs created in prior blocks. But transactions are
allowed to spend UTXOs created by prior transactions in the same block.
This doesn't fit with the existing query model, so instead of trying to
change it, allow the script verifier to take an additional set of known
UTXOs, and propagate this set from the block.
The metrics code becomes much simpler because the current version of the
metrics crate builds its own single-threaded runtime on a dedicated worker
thread, so no dependency on the main Zebra Tokio runtime is required.
