Add copy/paste execution strings for convenient builds

[lbakerchef]

Paste this into your shell for convenient builds!

cd && . load-omnibus-toolchain.sh && cd chef-server/omnibus && sudo chown -R vagrant ~/.bundle/ && bundle install --binstubs && bin/omnibus build chef-server -l internal

@lbakerchef, just a couple of thoughts on the docs:

• maybe use source ~/load-omnibus-toolchain.sh as an alternative to . load-omnibus-toolchain.sh; some people may not realize that the period character is used to source a file

@lbakerchef - this is helpful only first time the build is run. For all the subsequent builds we would run only the last command. It would help to get some clarification around that.

@PrajaktaPurohit - For the lazy approach, you can always just paste the same thing and it still works (it's what I do). I think it's 'idempotent' so it runs through the first commands quick if it's not necessary. The idea is to have one "always works, don't need to think" string you can just "paste and forget." "One execution string to rule them all and bind them." But I will add some clarification. Personally, this saves me a lot of time and effort, so I thought others would find it useful.

@christopher-snapp - The period (.) is in the original docs so that's what I used in the execution string. I will try to add a note as to what you are saying if I can figure out a way to do it without muddying the waters.
