* New resource view: ReplicationController -- scaffolding files

Signed-off-by: Roman <ixrock@gmail.com>

* fix: inappropriate names after copy-pasting

Signed-off-by: Roman <ixrock@gmail.com>

* update replication controller api types/spec, fix menu title

Signed-off-by: Roman <ixrock@gmail.com>

* items list + details list views (added contents from replication controllers), lint fixes

Signed-off-by: Roman <ixrock@gmail.com>

* allow to scale replication controllers

Signed-off-by: Roman <ixrock@gmail.com>

* switched for scaling replicas with `Slider` component instead of `Buttons+Input`
