* connect to the ups web ui after install and verify the proper certificate is being served
* rename `apchost` flag to `hostname`
* separate ports to additional flags (`sshport` `sslport`) with sane defaults
The code should auto-select the native ssl method if the ssl command is available on the UPS.
If this fails, install will drop back to the original install method used by this tool (which works on NMC2).
This was done for clearer separation of function. A subsequent update will (hopefully) make the SSL command more robust so it works for both NMC2 and NMC3.
The method for sending shell commands was also updated to use an interactive shell instead. This allows capturing responses of the commands which will be needed to deduce if devices are NMC2 or NMC3.
The NMC Security Wizard can also produce .p15 files that contain just a private key. Add this ability to this tool.
When the `create` function is used, both files will be outputted.
