v5.1.1

[prestonvanloon]

This release has a number of features and improvements. Most notably, the feature flag --enable-experimental-state has been flipped to "opt out" via --disable-experimental-state. The experimental state management design has shown significant improvements in memory usage at runtime. Updates to libp2p's gossipsub have some bandwidith stability improvements with support for IDONTWANT control messages.

⚠️ The gRPC gateway has been deprecated from Prysm in this release. If you need JSON data, consider the standardized beacon-APIs.
💡 This is our first release using pull request authors' entries from our CHANGELOG.md file.
❤️ Please give feedback in github issues or on discord.

Updating to this release is recommended at your convenience.
