charms should be able to provide a 'missing-hook' script

Bug Description

Rather than having a bunch of symlinks to one central controlling hook, we should simply have a 'missing-hook' hook that gets executed with the name of the missing hook as the first cmdline argument.

This would make it easier to write charms which apply configuration using other tools such as puppet or a more declarative charm-helper.

<imbrandon> would be really cool to have a hooks/missing hook
<imbrandon> that could get called if there was no other named hook
<hazmat> imbrandon, a whole charm with a single missing hook ... ick ;-)
<imbrandon> hahahah i was waiting for that :) it sounded good in my head and for like 5 miuntes, but the more i thought about it I tend to agree :) heh
<SpamapS> hazmat: so you'd rather have a whole charm with a single hook, and 20 symlinks?
<SpamapS> hazmat: because, thats whats there now, and its kind of ridiculous ;)
<hazmat> SpamapS, yeah.. because that's also discoverable what hooks its using
<hazmat> a single missing hook.. no idea
<SpamapS> at what point do you care?
<hazmat> the point where your debugging it
<hazmat> or modifying it
<SpamapS> If you're already debugging or modifying it
<SpamapS> you're editting the missing hook
<SpamapS> which isn't a useful hook without a clear routing switch/case of some kind
<SpamapS> Unless it calls a declarative charm helper thing.. which is what I think would be cool
<SpamapS> I mean, its already happening. Its just happening in a clunky way with symlinks
<SpamapS> because now you have to have the routing switch/case *AND* the symlinks
<imbrandon> hrm , declarative charm helpers and one hook .... hrm
<hazmat> SpamapS, as a charm author i can see that being nice.. as a farmer.. its nice to know what hooks are being used without having to dig through arbitrary src
<SpamapS> hazmat: As a one time chief farmer, and now occasional farmer.. I respectfully disagree. I still have to read the symlinked-to thing before I understand the charm... and often its not clear what is symlinked to.
