cluster.add_host does not respect insecure when non-interactive

[aburnheimer]

cluster.add_host does not seem to respect the --insecure option when used in rvc_exec calls, non-interactively:

$ rvc user:[email protected]
0 /
1 1.2.3.4/
> cd /1.2.3.4/my_datacenter/my_host
/1.2.3.4/my_datacenter/my_host> cluster.add_host -k new_cluster/ 5.6.7.8 -u jack -p splat
AddHost ZZ-TBD: SSLVerifyFault: Authenticity of the host's SSL certificate is not verified.
D: running ❲
   . . . command succeeds . . .

...as opposed to:

$ cat script_to_run.rvc
rvc_exec "cd /1.2.3.4/my_datacenter/my_host"
rvc_exec "cluster.add_host -k new_cluster/ 5.6.7.8 -u jack -p splat"
$ rvc user:[email protected] -s script_to_run.rvc
$ echo $?
0
$       # . . . command appears to succeed, but . . .

...in the status field of logs in the vSphere client for Windows running on 1.2.3.4, the following shows:

Authenticity of the host's SSL certificate is not verified.

Thanks much for looking into the issue!
