docs (deis-cli): removed sudo for consistency

fix(Vagrantfile): disable replacing of default insecure key
fix(contrib): use 1GB per VM

Most modern laptops have ~8GB of memory available to them. On OSX,
this is stretched even thinner due to boot2docker. Lowering the memory
requirement for each host back to CoreOS' default memory requirements
should allow us to use Vagrant on machines with less than 16GB of
memory.

stripping the file extension from a string.
re-revert "ref(tests): switch to example-dockerfile-http app"

example-dockerfile-http has switched over to ubuntu:trusty for better
compatibility with apps:run (busybox does not ship with bash).

This reverts commit ebded177705e257d8227a836bade85331d56f8d7.
