Ability to set custom prefix instead of: "/v1/kv/"

[xp-vit]

consul allows to have different vaults and have custom names for them e.g.:

"/secretvault/dev/" instead of "/v1/kv/". We need to provide the ability to be able to retrieve config values from non-default vaults. this parameter should be configurable in the constructor and per request, I think.

Hi @xp-vit! I've not been keeping up with recent Consul developments. Is it possible to link to the documentation for custom key / value prefixes? I couldn't see it immediately: https://www.consul.io/api/kv.html

Lines like this: https://github.com/cablehead/python-consul/blob/master/consul/base.py#L553 seem to suppose that your key-value store will be with the prefix "/v1/kv/", which will be true if it's created with this client (since it's hardcoded), but won't necessary be true if it was created in another manner. A settable prefix would be super useful in those cases.
