LeGo CertHub v0.15.0

[v0.15.0] - 2023-10-23

Warning
You must ensure your config.yaml is at least config_version: 1 prior to
installing or LeGo will not start.

Note: If you are new or don't have a config.yaml, one will be created for
you on the first run of LeGo.

Moving forward LeGo will enforce config_version but will migrate seemlessly
unless there are notes to the contrary. Notes will include specific needed
actions. To assist with changes across versions, all releases now include a
config.changelog.md which notes all changes, not just breaking changes.

If you are already on the previous version (0.14.1) you can just manually
insert config_version: 1 without any other changes. You should still
review the config default and example to ensure you have the options you
want.

This version also includes a bunch of other features, most of which revolve
around adding more security to LeGo.

Added

• Create config.yaml if one does not exist.
• Add strict enforcement of config.yaml schema version.
• Add auto update schema from 1 to 2. Older version 0 or unspecified
  version will need manual intervention (at a minimum config_version
  will need to be added).
• Add HTTP Strict Transport Security (HSTS) header by default. Config has
  an option to disable the header (disable_hsts).
• Add relatively strict Content-Security-Policy header, including nonces
  on scripts. Vite does not yet support nonces for style but I will add
  it later when it does.
• Add headers to prevent MIME type sniffing and iframes.
• Add frontend_show_debug_info config option to set frontend to show
  debug info and do some console.logging.
• Add ability to clear the update notification from the left side
  navigation bar.
• Add logout tooltip.
• Add theme toggle tooltip.
• Add data-preload on style, script, and link tags.
• Add timeout context on Cloudflare API calls.
• Include config.changelog.md in releases. This file details changes to
  config.yaml over time.

Changed

• Move theme toggle to just an icon in bottom right corner in footer.
• Rewrite frontend file handler on the Go backend. Needed to provide
  more consistent headers and nonce support.
• Update to Go 1.21.3, Node 18.18.2, and Vite 4.5.0.
• Update all other dependencies in frontend and backend.
• Update acme.sh script to 3.0.7 (adds a couple more dns providers).
• Update Cloudflare provider to utilize newest Cloudflare Go api.
• Some minor code cleanup.
• Rename cors_permitted_origins config option to
  cors_permitted_crossorigins.
• Minor navbar restyling.
• Change status/new version information and update frontend to properly
  show the changed information.
• Redact certain senstive information when the frontend is set to log
  debug info to the console.

Fixed

• Fix accidentally allowing all cross-origins by default. If no origins
  are specified, CORS is disabled.
• Explicitly set dockerbuild tool versions so binary releases and docker
  releases are built in the same way.

Removed

• Removed dockerfile generation of empty config file. This is now handled
  by the backend when it runs for the first time.
• Remove frontend Settings link to backend URL. Link just goes to a 404
  so there isn't really a point.
• Remove Roboto font include and move it to external files.
