History
Ruslan Aliev 3e44c42989 Introduce KRM based k8s applier 
The KRM based k8s applier solves multiple design problems
which were introduced in previous airshipctl generation,
making apply code and process more clear, reliable and
readable. In particular:
 * k8s applier now is a KRM function and it allows the
   end user to choose or implement desired backend for
   k8s apply operations;
 * the related amount of code was reduced by three times,
   multiple unused and unnecessary structs/interfaces/design
   patterns were removed or rewrited in more clean and efficient
   way;
 * removed cli-utils dependency from airshipctl;
 * fixed several bugs and code issues, such as incorrect printing
   of tables, duplicated unit tests, improper generation and applying
   inventory config map, etc;
 * cli-utils version used in KRM function was bumped to 0.26.0;
 * phases with duplicated k8s resources were removed or fixed;
 * unit test coverage increased to 83.1%;
 * KRM function logs were integrated with klog library which allows
   to observe logs directly from cli-utils and other dependent libs.

Applier

This is a KRM function which applies resources to k8s using cli-utils with appropriate options.

Function implementation

The function is implemented as an image, and built using make docker-image-applier.

Function configuration

As input options, the KRM function receives a struct with apply options. See the ApplyConfig struct definition in v1alpha1 airshipctl API for the documentation.

Function invocation

The function invoked by airshipctl command via airshipctl phase run:

airshipctl phase run <phase_name>

if appropriate phase has k8s_apply executor defined.
