feat: adds descriptions to feature checks and add them to logs

[cmintey]

What type of PR is this?

• feature

What this PR does / why we need it:

Adds some additional logging around our application features on startup. This is similar to the app checks in the admin UI, but I think its nice to log them as well and the descriptions can be helpful in debugging. We could also show these descriptions in the app checks on the settings page, but we'd need to consider translations.

Also, instead of excluding secrets from the dump, this PR will instead mask the secrets with "*****" or if the secret is None, will show it as null. This again will help with debugging to show when values are set without logging secrets.

Which issue(s) this PR fixes:

Not an issue, but a discussion: #3334 (comment)
This doesn't directly fix it, but hopefully will help in debugging
