Dynamic master key

[mtrezza]

New Feature / Enhancement Checklist

• [x] I am not disclosing a vulnerability.
• [x] I am not just asking a question.
• [x] I have searched through existing issues.

Current Limitation

The master key is set on dashboard start and cannot be changed without a dashboard restart. This is disadvantageous when periodically rotating the keys because a key rotation also requires a dashboard restart.

Feature / Enhancement Description

• Allow to set an async function for the master key instead of a string.
• Add the master key to the internal cache with a TTL, so that the function is not called every time the master key is validated

Example Use Case

New Parse Dashboard options:

{
  masterKey: async () => await getKey(),
  masterKeyTtl: 3600,
}

Alternatives / Workarounds

Dashboard restart.

Should this have a caching mechanism as well?

[mtrezza]

You are right, I removed that from the initial description, but re-added it now.
