Implement --webpage option for PSSH

[jcmcken]

Create a simple, deployable webpage containing PSSH task data.

So something like...

$ pssh $OTHER_OPTS --webpage

Exported web slug to 'pssh-bf0ac3bb906a96481506dc91c051a8fe.tar.gz'

$ tar xfz pssh-bf0ac3bb906a96481506dc91c051a8fe.tar.gz
$ tree pssh/
pssh
|-- 01-13-2012-01:23:48.html
-- static |-- pssh.css -- pssh.js

1 directory, 3 files
$ cd pssh; python -m SimpleHTTPServer
Serving HTTP on 0.0.0.0 port 8000 ...

[jcmcken]

Call it --to-html with the companion --http-root option, which indicates the directory to drop the html file.

E.g.

pssh -h hostlist.txt --script do_stuff.sh --to-html --http-root /tmp
