-s in secrets engine makes them unreadable

[mike-bailey]

At least the Logical endpoints improperly URL encodes - and thus if you have something, say, called secrets-kv it won't be able to list, read, etc as it'll encode - and fail. Vault CLI doesn't encode -.

I tapped the list functions from logical to client and confirmed:

{:list=>true}

"/v1/secrets%2Dkv"

#<URI::HTTPS https://websitehere/v1/secrets%2Dkv?list=true>```
