providers.repos.secretPatterns (keys, values) apply to every config file
type; spring.secretPatterns overrides them list by list. A repo's
.lazysecrets.yaml takes the same layout. Each list comes from the first
that sets it: the repo's for the type, the repo's, the config's for the
type, the config's, the defaults.
