Make more command line options scriptable.

Migrate from this style of usage:

%key-manager -R
Which server would you like to revoke? <servername>

to

%key-manager -R <servername>

so that maintenance may be scripted.

mgrall options which need it:
-J
-a
-A
-r ??? (since it needs user and host??)
-R

root options which need it:
-n
-N
-d
-D
-p

Ideally, the command line parsing would recognize if the 'old style', 'interactive' options would be needed, or if the 'new style' was sufficient.

For security reasons, and because it's duplicated by the various 'bulk' options, this isn't needed EVERYWHERE... -i comes to mind because you need to enter a password, and having that on the command line is bad.
