feat: Add Xatu Sentry (#466)

Adds support for [Xatu](https://github.com/ethpandaops/xatu) in Sentry
mode. Similarly to Ethereum Metrics Exporter, Xatu Sentry can be enabled
globally, or per client pair.

Note: This PR only enables "Sentry". Xatu Server/Clickhouse etc will
need to run outside of Kurtosis for this to be useful.
