Unable to Shut Off Instance while it is Paused

[Amogh]

1. Login to DevStack as admin user
2. Create the Instance and from Actions drop down click on "Pause Instance"
3. Observe that Instance is in Paused state.
4. From more Actions click on "Shut Off Instance" and confirm the PopUP.
5. Observe that "Error: Unable to shut off instance" is displayed.

Expected Result: Instance needs to shutoff properly, else Shutoff option needs to be removed when Instance is in "Paused State".

'nova stop' rejects stopping a paused VM. StopInstance 'allowed' method should not include the PAUSED state.

    Avoid shutting off a paused VM instance

    Currently, "Shut Off Instance" option is enabled even on a paused VM instance
    which results in an error that says "Error: Unable to shut off instance".
    With this commit, we are removing the option to shut off a paused VM instance.
