Add get_os and get_os_release functions, refacter get_os_type

get_os:
Returns the exact operating system

get_os_release:
Returns the release of the operating system

Switch get_os_type to use an argument for the target location and also ensure
that it gets checked.

Fix dynamic partition to use its own function

I discovered that bash wasn't setting the environment variables correctly and
realized I need to refactor how I do this. Now I have a map_partition to figure
out the exact path for a specific partition.

NOTE: fstabs are currently broken because of this addition

Add optional support for no /boot partition

Allow for more flexibility for which partitions you need or what. It will allow
for four different partition layouts depending on whether you want a swap
partition or booting a kernel outside of the VM.

Also merge the partition mapping for root_dev, boot_dev, & swap_dev entirely...

Make regex more clear and only do this on the end of the string

Add VOL_ID and VOL_TYPE back for export

Move OS detection to common.sh to make it portable for other scripts

Also refactor how we use it in interfaces

Create IMAGE_DEBUG variable to enable debugging output

DEBUG_LEVEL isn't working yet in ganeti [1], so lets add an option so we can at
least use something.

Make it optional whether to create and use a swap partition

Refactor grub install into a custom script

We only need to use grub for tarball based installs since images should include
a disk with grub already installed.

allow for the location of IMAGE_DIR to be changed by the user

Check to make sure the first partition exists

Add --with-defaults-dir option

Some distros don't use /etc/defaults

Format the 3 volumes and mount them correctly

Add basic support for installing via a CD

Check for various important programs and set variables for them
