[BUG] API Consistency between List/X Plural/Singular

[verdantvestibule]

The Bugs

Consistency

Some backend configuration and API consistency issues. Vault is not the most consistent with their API either, but they do pick one: plural or singular, and do LIST/GET on that endpoint... here you are sometimes doing plural, sometimes plural and signular.

• roles is LIST, and READ,UPDATE
• certs is LIST, cert is READ
• issuer is READ,UPDATE

Non-Existant Paths

• issuers is listed in UnauthenticatedPaths but does not exist.

Seal-Wrap

• role/* doesn't really need to be seal-wrapped. config is where private keys live
