Because we are using the building platform's "yum" to do the initial
install into the chroot, it is affected by the base-system's
/etc/yum.conf.
pip-and-virtaulenv in I82acb865378a0fa5903a6267bfcee0e2962eced0 added
"exclude=python-pip..." in /etc/yum.conf to stop the package manager
overwriting the installed pip. Now our CI images have built with
this, we are now picking up this exclude on centos. Since on F24
dnf->python->python-pip we end up failing to build the the chroot
because python-pip can not be satisifed. In a general sense, however,
this could be caused by any configuration put into /etc/yum.conf that
is incompatible with installing into the chroot.
yum has the option to disable all excludes which is used here. This
seems to be the best way to isolate the chroot install from any
excludes that may have been done on the base system for various
reasons. I did consider using a completely separate yum.conf we ship
with dib ... but let's start simple.
This should fix the current gate failures on centos

The previous commit removes dkms from the base element, which
means the centos elements should no longer have a dependency on
EPEL. Therefore, we should not hardcode the epel dependency. It
can still be included in image builds as desired by using the epel
element explicitly.

The use of dkms in base was actually removed long ago in
Ic2c345bf9f0738dadae611194e263d3a5d424a3e and it is creating an
unnecessary dependency on EPEL for the centos elements.

Move element-info from a wrapper script to a standard entry-point
console_script.
Update the documentation to explain how to run it for development. I
don't think we should support the idea that you can check-out the code
and run ./bin/disk-image-create -- it has dependencies (dib-utils,
etc) and needs to be run from a virtualenv (this is what CI in the
gate does). A follow-up can clean-up some of the path munging stuff
we have for this in disk-image-create.

Block device handling can be somewhat complex - especially
when taking things like md, lvm or encryption into account.
This patch factors out the creation and deletion of the local
loop image device handling into a python library.
The main propose of this patch is to implement the needed
infrastructure. Based on this, more advanced functions can be added.
Example: (advanced) partitioning, LVM, handling different boot
scenarios (BIOS, UEFI, ...), possibility of handling multiple images
(local loop image, iSCSI, physical hard disk, ...), handling of
different filesystems for different partitions / LVs.

Using the explicit variables, these elements don't have to walk the
path to find the files in other elements; they can extract it directly
Change-Id: I0a64b45e9f2cfa28e84b2859d76b065a6c4590f0
These new variables are a list of elements chosen for the build along
with their full paths. For Python elements, IMAGE_ELEMENT_YAML is a
YAML formatted list that can be easily parsed. For bash elements,
"get_image_element_array" will produce an associative-array of the
same (working around lack of array export in Bash).
This list is intended for consumption of elements who need to copy
files from other elements, such as pkg-map and svc-map. As discussed
in I2a29861c67de2d25c595cb35d850e92807d26ac6, this list has already
been pruned and had overrides processed, so it is safe to simply walk
over this list with no further processing.
Since we're presenting the element list in a couple of different ways,
we combine it all into the element-info script. It will output an
eval-able string that declares the appropriate variables.
I've added some inline documentation so they still appear in grep.
The documentation is updated with examples, and moved to a more
appropriate location as a sub-section of the element sytle guide.
To test this out, use the associative-array in generate_hooks, where
we can now find the element's directory without searching.

This is a re-factor of element_dependencies to achieve two things --
centralising override policy and storing path names.
Firstly we want to make the override policy for elements completely
explicit. Currently, elements that wish to copy parts of other
elements walk ELEMENTS_PATH themselves and look for elements in
IMAGE_ELEMENT. How they handle duplicate elements can differ, leading
to inconsistent behaviour.
We introduce logic in element-info to find elements in each of the
directories in ELEMENT_PATHS in *reverse* order -- that is to say,
earlier entries in the paths will overwrite later ones.
For example
ELEMENT_PATHS=foo:bar:baz
will mean that "foo/element" will override "baz/element", since "foo"
is first. This should be sane to anyone familiar with $PATH.
Documentation is clarified around this point and a test-case is added.
The second thing is that we want to keep the complete path of the
elements we have chosen. We want the aforementioned elements that
walk the element list to use these canonical paths to pickup files;
this way they don't need to make local decisions about element
overrides, but can simply iterate a list and copy/merge files if they
exist.
A follow-on change (I7092e1845942f249175933d67ab121188f3511fd) will
expose this data in a separate variable that can be parsed by elements
(a further follow-on I0a64b45e9f2cfa28e84b2859d76b065a6c4590f0
modifies the elements to use this information). Thus this does not
change the status-quo -- elements that are walking ELEMENTS_PATH
themselves and can/will continue doing that.

IPv6 privacy extensions can cause issues by preferring a temporary
network over a public one. This preference may limit connectivity
in certain situations. An example of a connectivity issue can be
seen where the command ``traceroute6`` fails or misses all hops
while other traffic to a given domain with a "AAAA" record may
succeed. To resolve this issue the IPv6 privacy extensions have
been disabled.
