Allow token authorization instead of basic (requires WHM access)

[tturnerdev]

Authenticate and call install_ssl via WHM API instead of cPanel UAPI.
Requires WHM access, common for reseller accounts (not shared hosting)
Using a token is safer than basic authentication, allows access control, and revoke.

I think there's a problem here:

elseif (!$GLOBALS['token'] && !$response->status ) {
    $msg = json_encode($response);
    err("The CURL call returned valid JSON, but reported errors: $msg");
} elseif ( !$response->result->status ) {
    $msg = json_encode($response);
    err("The CURL call returned valid JSON, but reported errors: $msg");
}

when response is good, and the token method is not used, elseif ( !$response->result->status ) checks a condition on an invalid variable $response->result->status.

A solution may be this:

elseif (!$GLOBALS['token']){
    if(!$response->status ) {
        $msg = json_encode($response);
        err("The CURL call returned valid JSON, but reported errors: $msg");
    }
} elseif ( !$response->result->status ) {
    $msg = json_encode($response);
    err("The CURL call returned valid JSON, but reported errors: $msg");
}
