Subject: [PATCH] zebrad: remove git pin on metrics dependency

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.
