Zrok

FIX: Remove extraneous share token prepended to OAuth frontend redirect.

FEATURE: The `sdk` package now includes a `sdk.Overview` function, which returns a complete description of the account attached to the enabled environment. Useful for inventorying the deployed shares and environments (https://github.com/openziti/zrok/issues/407)

CHANGE: The `zrok access public` frontend configuration format has changed and now requires that the configuration document include a `v: 2` declaration. This frontend configuration format is now versioned and when the code updates the configuration structure, you will receive an error message at startup, provoking you to look into updating your configuration (https://github.com/openziti/zrok/issues/406)

CHANGE: The title color of the header was changed from white to flourescent green, to better match the overall branding

CHANGE: Tweaks to build and release process for logging and deprecations. Pin golang version at 1.21.3+ and node version at 18.x across all platforms

CHANGE: Improvements to email invitation sent in response to `zrok invite` to correct broken links, some minor HTML issues and improve overall deliverability (https://github.com/openziti/zrok/issues/405)

CHANGE: Added warning message after `zrok invite` submit directing the user to check their "spam" folder if they do not receive the invite message.

FEATURE: OAuth authentication with the ability to restrict authenticated users to specified domains for `zrok share public`. Supports both Google and GitHub authentication in this version. More authentication providers, and extensibility to come in future `zrok` releases. See the OAuth configuration guide at `docs/guides/self-hosting/oauth/configuring-oauth.md` for details (https://github.com/openziti/zrok/issues/45, https://github.com/openziti/zrok/issues/404)

CHANGE: `--basic-auth` realm now presented as the share token rather than as `zrok` in `publicProxy` frontend implementation

FEATURE: New `--backend-mode caddy`, which pre-processes a `Caddyfile` allowing a `bind` statement to work like this: `bind {{ .ZrokBindAddress }}`. Allows development of complicated API gateways and multi-backend shares, while maintaining the simple, ephemeral sharing model provided by `zrok` (https://github.com/openziti/zrok/issues/391)

CHANGE: `--backend-mode web` has been refactored to utilize Caddy as the integrated web server. This provides for a much nicer web-based file browsing experience, while maintaining the existing web server facilities (https://github.com/openziti/zrok/issues/392)

CHANGE: Updated the golang version for release builds to `1.21.0` and the node version to `18.x`

CHANGE: Added `FrontendEndponts` to `sdk.Share`, returning selected frontend URLs to callers of `sdk.CreateShare`

CHANGE: Added a short alias `-b` for `--backend-mode` to improve CLI ergonomics (https://github.com/openziti/zrok/issues/397)

FEATURE: New health check endpoint (`/health`), which verifies that the underlying SQL store and metrics repository (InfluxDB, if configured) are operating correctly (https://github.com/openziti/zrok/issues/372)

CHANGE: Updated to golang v1.21.0 and node v18.x

FIX: `zrok admin bootstrap` and `zrok enable` both broken with latest OpenZiti releases (tested with `v0.30.0`); updated to latest OpenZiti golang SDK (https://github.com/openziti/zrok/issues/389)

FIX: `zrok status`, `zrok enable`, `zrok config`, etc. were all causing a panic when used on systems that had no previous `~/.zrok` directory (https://github.com/openziti/zrok/issues/383)
