Add Apt (Deb/Ubuntu) installation instructions for Helm 2

Add Warning when installing or upgrading a deprecated chart - replacing PR #8262

Consider namespace when comparing resources

Adding init flad to skip adding repos

The stable charts repository is nearing the end of its life. Once
that has happened those who attempt to run helm init will get an
error. This flag provides a means to still use Helm v2 after the
stable charts repository is gone.

A secondary situation is that Helm v2 can be used in environmnets
without a network connection.

Adding a counter to the dependencies cache

The cache needed to be cleared due to an issue presented when the
source for one dependency moved from one place to another. To
accomplish this we add a counter. This is similar to the recommendation
in the CircleCI documentation on caching

Fix issue with sorting pod lists

Signed-off-by: Matt Johnson <mjohnson@sonatype.com>

The sorting previously used the selfref which contained the name
on the end for all cases except pods. In that case the selfref
was to pods and not the specific pod. This caused an issue where
multiple pods had the same selfref used as the key for softing.

The objects being sorted are tables that each have one row. In the
new setup the key is the first cells value from the first and only
row. This is the name of the resource.

Note, the Get function now requests a table. The tests have been
updated to return a Table type for the objects.

Restores display of object status when displaying helm status

Changes to the Kubernetes API server and kubectl libraries caused
the status to no longer display when helm status was run for a
release. This change restores the status display.

Generation of the tables for display was moved server
side. A request for the data as a table is made and a kubectl
printer for tables can display this data. Kubectl uses this setup and
the structure here closely resembles kubectl. kubectl is still
able to display objects as tables from prior to server side
printing but only prints limited information.

Note, an extra request is made because table responses cannot be
easily transformed into Go objects for Kubernetes types to work
with. There is one request to get the resources for display in
a table and a second request to get the resources to lookup the
related pods. The related pods are now requested as a table as
well for display purposes.

This is likely part of the larger trend to move features like
this server side so that more libraries in more languages can
get to the feature.

* align both formats behaviors and now they will just differ in how to discover their paths
* add coverage for exports format and fix expected assertions for parent-child format to match the logic child values always wins
* just partially revert dda84976, this way parents values could be overridden when coalescing
* after getting better coverage we were able to refact both formats behaviors by merging their propagation logics into a single code path.
