Feature request: Run external command to dynamicaly generate PTYPES

[Google Code Exporter]

Say for example you have something like this:

<VIEW name="configure-view">
        <COMMAND name="phonegroup"
                help="Select a phonegroup to configure"
                view="configure-phonegroup-view"
                viewid="phonegroup=${phonegroup}">
                <PARAM name="phonegroup"
                       help="Phonegroup Name"
                       ptype="STRING"/>
        </COMMAND>
</VIEW>

you enter the configure view and type phonegroup, hit tab and get the following:
(config)# phonegroup
  String  Phonegroup Name

What I would like to do, is actually list out all phonegroups (or whatever i'm 
configuring), for quick tab completion.

It would be great to be able to define a new PTYPE, where instead of a fixed 
pattern, it ran a command instead, that will return the possibilities for that 
PTYPE.

What I would like to be able to do, is type phonegroup, hit tab, and see

(config)# phonegroup
  String  Phonegroup Name (foo, bar, bin, baz, xyz)

So then I could type 
(config)# phonegroup x <tab>

and it would complete it to be xyz

so maybe a new PTYPE method can be added, method="command" and then specify 
command="/path/to/script"

It would return a list of possible completions in a specific format.  klish 
would have to check against the list of completions for tab completion 
candidates.

To create script generated completion you can use dynamic variables and 
"completion" field of PARAM tag.

<VAR name="ETH"
        help="Ethernet interfaces system prefix"
        value="eth"/>

<VAR name="POSSIBLE_ETH"
        help="Displays possible ethernet numbers (with VLANs)" dynamic="true">
<ACTION>
iface-possible ${ETH}
</ACTION>
</VAR>

<PARAM name="sifnum" ptype="IFACE_NUM" help="Interface number" 
completion="${POSSIBLE_IFACE}"/>
