Epic: Zebra Stable Release Candidate

[mpguerra]

This epic tracks the requirements we want to meet in order to tag a release candidate of Zebra ahead of a stable release.

Stable Release Candidate Goals

1. This version of Zebra is a fully-validating node that implements all the (relevant) consensus rules (that we’re aware of) and actively contributes to the Zcash network by relaying transactions and blocks.
2. Will not have an adverse impact on the Zcash network as a whole or on other nodes (i.e. zcashd nodes)
3. No known significant security issues (e.g. RCEs, DoS bugs)
4. We are comfortable with it being audited, and for the results of that audit to be published
5. Performance
   1. Improves the network through fast propagation
   2. Zebra can connect to ¼ of the network
