Initial add of gentoo support for diskimage-builder uses upstream's stage4 images, includes all the needed bells and whistles for openstack on kvm. Change-Id: Ibca43173c30c2a74a73a2e2d9dd6d6d832c62694 Closes-Bug: 1530911

Use a Gentoo cloud image as the baseline for built disk images. The images are
located in profile specific sub directories:

* There are very frequently new automated builds that include changes that
happen during the product maintenance. The download directories contain an
unversioned name and a versioned name. The unversioned name will always

Optionally remove portage files Optionally remove portage files, so that we can cache package and keep the portage directory around, specifically for nodepool. This also adds a section to the Gentoo readme about the variable and renames the 00-gentoo-distro-name environment file to a more appropriate name of 00-gentoo-envars. Also brought up was the location of the gentoo-releng.gpg file, this has been moved and the refrencing paths updated. Change-Id: I20c91b36082828faa1ca481585acc5f9933211e1

enable caching for gentoo builds To facilitate this I've created two new environment variables to set the environment and default options for package actions. eval is needed for the export as it preserves quotes.

* You can set the `GENTOO_PORTAGE_CLEANUP` environment variable to False to
disable the clean up of portage repositories (including overlays). This
will make the image bigger if caching is also disabled.
Update Gentoo element for element changes There have been a few changes over the past few months, here we make the following changes. * change from backtrack=99 to complete-graph as a more correct flag * make python version selection more in line with what gentoo supports * set up python before stuff gets pip installed * ensure we have the proper pip so we can install pip packages as root * ensure we have the proper use flags for the disk formatting changes * set DIB_RELEASE like other distros * fix openssh-server element for gentoo Change-Id: I17202de3016616ce34c8cbead7d0fb047a64e96b

* You can enable overlays using the `GENTOO_OVERLAYS` variable. In it you
should put a space separated list of overlays. The overlays must be in the
official overlay list and must be git based.

* `GENTOO_EMERGE_ENV` is a bash array containing default environment
variables for package install, you can override it with another bash array.
* `GENTOO_EMERGE_DEFAULT_OPTS` can be set to control the default options
passed to emerge for all package actions, this includes operations like
depclean and preserved-rebuild.
