Fixes#4191#4993
This bumps Kubernetes client-go to the latest v0.19.2 (We had to switch directly to 1.19 because of this issue). Bumping to v0.19.2 required upgrading to smi-sdk-go v0.4.1. This also depends on linkerd/stern#5
This consists of the following changes:
- Fix ./bin/update-codegen.sh by adding the template path to the gen commands, as it is needed after we moved to GOMOD.
- Bump all k8s related dependencies to v0.19.2
- Generate CRD types, client code using the latest k8s.io/code-generator
- Use context.Context as the first argument, in all code paths that touch the k8s client-go interface

This moves Prometheus as a add-on, thus making it optional but enabled by default. The also make `linkerd-prometheus` more configurable, and allow it to have its own life-cycle for upgrades, configuration, etc.
This work will be followed by documentation that help users configure existing Prometheus to work with Linkerd.
**Changes Include:**
- moving prometheus manifests into a separate chart at `charts/add-ons/prometheus`, and adding it as a dependency to `linkerd2`
- implement the `addOn` interface to support the same with CLI.
- include configuration in `linkerd-config-addons`
**User Facing Changes:**
The default install experience does not change much but for users who have already configured Prometheus differently, would need to apply the same using the new configuration fields present in chart README
* Moves Common templates needed to partials
As add-ons re-use the partials helm chart, all the templates needed by multiple charts should be present in partials
This commit also updates the helm tests

* add tracing add-on helm chart
Tracing sub-chart includes open-census and jaeger components as a sub-chart which can be enabled as needed
* Updated Install path to also install add-ons
This includes new interface for add-ons to implement, with example tracing implementation
* Updates Linkerd install path to also install add-ons
Changes include:
- Adds an optional Linkerd Values configmap which stores add-on configuration when add-ons are present.
- Updates Linkerd install path to check for add-ons and render their sub-charts.
- Adds a install Option called config, which is used to pass confiugration for add-ons.
- Uses a fork of mergo, to over-write default Values with the Values struct generated from config.
* Updates the upgrade path about add-ons.
Upgrade path now checks for the linkerd-values cm, and overwrites the default values with it, if present.
It then checks the config option, for any further overwrites
* Refactor linkerd-values and re-update tests
also adds relevant nil checks
* Refactor code to fix linting issues
* Fixes an error with linkerd-config global values
Also refactors the linkerd-values cm to work the same with helm
* Fix a nil pointer issue for tests
* Updated Tracing add-on chart meta-data
Also introduced a defaultGetFiles method for add-ons
* Add add-on/charts to gitignore
* refactor gitignore for chart deps
* Moves sub-charts to /charts directly
* Refactor linkerd values cm
* Add comment in linkerd-values
* remove extra controlplanetracing flag
* Support Stages deployment for add-ons along with tests
* linting fix
* update tracing rbac
* Removes the need for add-on Interface
- Uses helm loading capabiltiies to get info about add-ons
- Uses reflection to not have to unnecessarily add checks for each add-on type
* disable tracing flag
* Remove dep on forked mergo
- Re-use merge from helm
* Re-use helm's merge
* Override the chartDir path during tests
* add error check
* Updated the dependency iteration code
Currently, the charts directory, will not have the deps in the repo. So, Code is updated to read the dependencies from requirements.yaml
and use that info to read templates from the relevant add-ons directory.
* Hard Code add-ons name
* Remove struct details for add-ons
- As we don't use fields of a add-on struct, we don't have them to be typed. Instead we can just use the `enabled` flag using reflection
- Users can just use map[string]interface{} as the add-on type.
* update unit tests
* linting fix
* Rename flag to addon-config
* Use Chart loading logic
- This code uses chart loading to read the files and keep in a vfs.
- Once we have those files read we will then use them for generation of sub-charts.
* Go fmt fix
* Update the linkerd-values cm to use second level field
* Add relevant unit tests for mergeRaw
* linting fix
* Move addon tests to a new file
* Fix golden files
* remove addon install unit test
* Refactor sub-chart load logic
* Add install tracing unit test
* golden file update for tracing install
* Update golden files to reflect another pr changes
* Move addon-config flag to recordFlagSet
* add relevant tracing enabled checks
* linting fix
