Rotate logged in host api key

[doodlesbykumbi]

Desired Outcome

Rotating your own role's API key in Conjur requires that the request include basic authentication credentials to verify that the user has positive control of either the current password or API key.

Currently there is no way to configure the Golang CLI to send basic authentication for the rotate API key request, so it is not possible to rotate your own API key with the CLI.

Note, it is possible to rotate another role's API key that your role has update privilege for.

Implemented Changes

Change command behavior of conjur host rotate-api-key without parameters to rotate the currently logged in host's api key, the same as conjur user rotate-api-key without parameters

It seems if a user is logged in and ran 'conjur host rotate-api-key' it would also rotate the user's api key. I'm thinking in this case maybe we should fail with an error since that's probably not what the user wants to happen. They may be expecting usage info or something instead.

Good point, the same is also true for conjur host rotate-api-key. This PR is addressing the particular reported bug. Perhaps we can address that in a separate PR

Almost there, just one tiny typo ;)
