Description of problem:
`fence_rhevm` requires `--ssl` option even when `--ssl-insecure` or `--ssl-secure` is present.

In `fence_vmware_soap` and `fence_cisco_ucs`, passing the `--ssl-secure` or `--ssl-insecure` option implies the `--ssl` option. If you pass `--ssl_insecure`, the URL is automatically prefixed with `https:`.

`fence_rhevm` does not work this way in the latest RHEL release of `fence-agents-rhevm`. In the `send_command()` function, `url` is set to `https:` if and only if the `--ssl` option is set. From `fence-agents-rhevm-4.0.11-84.el7.x86_64`:

~~~
def send_command(opt, command, method="GET"):
        ## setup correct URL
        if opt.has_key("--ssl"):
                url = "https:"
        else:
                url = "http:"
~~~

The `send_command()` function has been modified in the upstream Github repository in version 4.0.12 to accept any of `--ssl`, `--ssl-secure`, or `--ssl-insecure`, making its behavior more consistent with that of other fence agents.

~~~
def send_command(opt, command, method="GET"):
    ## setup correct URL
    if opt.has_key("--ssl") or opt.has_key("--ssl-secure") or opt.has_key("--ssl-insecure"):
        url = "https:"
    else:
        url = "http:"
~~~

The upstream change was committed in https://github.com/ClusterLabs/fence-agents/commit/14f6c3bc1e60e038c0b4daa87b1d0bda0d873661.
