vagrant/bootstrap.sh: silence wget output

The way vagrant streams the output of the progress indication of wget is
super annoying. So this adds the -q flag to reduce the noise.

vagrant/bootstrap.sh: silence wget output
vagrant: add zerocloudrc

This file contains the necessary environment variables to use swift and
zpm clients with the machine created by this vagrant script. Just
`source zerocloudrc` to use it.
added REST interface for POST

first REST interface support added, yay!
we now support POSTing stuff to arbitrary zapp archives
using `open` version or proper `X-Zerovm-Execute` header you can POST stuff into existing zapp
example:

	POST /account/container/my_zapp-0.1/my_zapp.zapp

the zapp should expect to get a POST request, which means:
- it should have { "device": "stdin" } without a "path" property, it will recieve the payload there
- it should have some other meaninful channels configured, for example { "device": "stdout" }
- it can use job-chaining to launch another sub-job
- it can use channels connected to containers to query the containers and create dynamic sub-jobs
- etc. etc.

there are still some caveats that will be probably sdressed soon, for example: the job-chained zapp cannot recieve the POST payload instead of API endpoint zapp

vagrant/README: add a note about zerocloudrc
vagrant/README: add note to restart devstack

Once everything is installed and configured, you need to bounce devstack
for zerocloud and everything to work. This adds instructions for the
user/developer to do that.
