Moved 80% of Foreman deploy.sh into functions

To help with readability and troubleshooting, the 80% of the
script that was not in a function were added to functions
based on logical blocks.

Neither functional nor order of execution changes were made
to the script.

Since most of the file and other Foreman CI scripts use a
2 space indent, that was also applied uniformly across the
file.
