* Refactor downloads to use download role directly
Also disable fact delegation so download delegate works acros OSes.
* clean up bools and ansible_os_family conditionals
* Adding yaml linter to ci check
* Minor linting fixes from yamllint
* Changing CI to install python pkgs from requirements.txt
- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements
Migrate older inline= syntax to pure yml syntax for module args as to be consistant with most of the rest of the tasks
Cleanup some spacing in various files
Rename some files named yaml to yml for consistancy
* Add restart for weave service unit
* Reuse docker_bin_dir everythere
* Limit systemd managed docker containers by CPU/RAM. Do not configure native
systemd limits due to the lack of consensus in the kernel community
requires out-of-tree kernel patches.

Add upload tag allow users to exclude distributing images across nodes
when running with the download tag set.
Add related tags and update docs as well.

When download_run_once with download_localhost is used, docker is
expected to be running on the delegate localhost. That may be not
the case for a non localhost delegate, which is the kube-master
otherwise. Then the dnsmasq role, had it been invoked early before
deployment starts, would fail because of the missing docker dependency.
* Fix that dependency on docker and do not pre download dnsmasq image
for the dnsmasq role, if download_localhost is disabled.
* Remove become: false for docker CLI invocation because that's not
the common pattern to allow users access docker CLI w/o sudo.
* Fix opt bin path hack for localhost delegate to ignore errors when
it fails with "sudo password required" otherwise.
* Describe download_run_once with download_localhost use case in docs
as well.

When setting permission for containers download/upload dir we're
using `ansible_ssh_user`. But if playbook is executed without
user being explicitly set `ansible_ssh_user` may be undefined.
In such situations dir ownership will default to `ansible_user_id`
Closes: #644
* Add download_localhost for the download_run_once mode, which is
use the ansible host (a travis node for CI case) to store and
distribute containers across cluster nodes in inventory.
Defaults to false.
* Rework download_run_once logic to fix idempotency of uploading
containers.
* For Travis CI, enable docker images caching and run Travis
workers with sudo enabled as a dependency
* For Travis CI, deploy with download_localhost and download_run_once
enabled to shourten dev path drastically.
* Add compression for saved container images. Defaults to 'best'.

Add one more step (task) to containers download/upload sequence -
copy saved .tar containers to ansible host (delegate_to: localhost).
Then upload images to target nodes. It uses synchronize module so
if ansible host (localhost) is the same host as kube-master[0] then
new task causes no issues and the copy to localhost process is
basically skipped.
* Don't push containers if not changed
* Do preinstall role only once and redistribute defaults to
corresponding roles

"else omit" is causing problems in this expression. Replacing
it with more strict "inventory_hostname" fixes the issue and
handles `download_run_once` as expected.
Closes issue #514
* Add the retry_stagger var to tweak push and retry time strategies.
* Add large deployments related docs.

Move version/repo vars to download role.

if enabled.

This should make things a little more composable,
by making these roles meta roles that perform no
actions by default we allow each role to own its own
resources.
using a shared folder can cause race conditions for the download
role as it tries to download files on all the nodes to the same
shared path. This adds a flag to run the tasks in the download
role on just one node.
