Configuration Secret
The "configuration secret" is a secret stored in Vault that contains global Pico configuration parameters that are considered too sensitive for environment variables or command-line flags.
Git Credentials
When Pico initialises, if you aren't using SSH for Git authentication, Pico will
read the config secret for GIT_USERNAME and GIT_PASSWORD. Pico will use
these to pull the configuration repository.
Global Environment Variables
Any key prefixed with GLOBAL_ will be passed to every target as an environment
variable. This is useful for log levels, dev/prod switches, feature flags or any
sort of shared credentials and secrets used by many or all targets.
