* Bump proxy-init to v1.3.2
Bumped `proxy-init` version to v1.3.2, fixing an issue with `go.mod`
(linkerd/linkerd2-proxy-init#9).
This is a non-user-facing fix.
## edge-20.1.3
* CLI
* Introduced `linkerd check --pre --linkerd-cni-enabled`, used when the CNI
plugin is used, to check it has been properly installed before proceeding
with the control plane installation
* Added support for the `--as-group` flag so that users can impersonate
groups for Kubernetes operations (thanks @mayankshah160!)
* Controller
* Fixed an issue where an override of the Docker registry was not being
applied to debug containers (thanks @javaducky!)
* Added check for the Subject Alternate Name attributes to the API server
when access restrictions have been enabled (thanks @javaducky!)
* Added support for arbitrary pod labels so that users can leverage the
Linkerd provided Prometheus instance to scrape for their own labels
(thanks @daxmc99!)
* Fixed an issue with CNI config parsing

### Problem
Field omissions for workload objects are not respected while marshaling to JSON.
### Solution
After digging a bit into the code, I came to realize that while marshaling, workload objects have empty structs as values for various fields which would rather be omitted. As of now, the standard library`encoding/json` does not support zero values of structs with the `omitemty` tag. The relevant issue can be found [here](https://github.com/golang/go/issues/11939). To tackle this problem, the object declaration should have _pointer-to-struct_ as a field type instead of _struct_ itself. However, this approach would be out of scope as the workload object declaration is handled by the k8s library.
I was able to find a drop-in replacement for the `encoding/json` library which supports zero value of structs with the `omitempty` tag. It can be found [here](https://github.com/clarketm/json). I have made use of this library to implement a simple filter like functionality to remove empty tags once a YAML with empty tags is generated, hence leaving the previously existing methods unaffected

* Enable mixed configuration of skip-[inbound|outbound]-ports using port numbers and ranges (#3752)
* included tests for generated output given proxy-ignore configuration options
* renamed "validate" method to "parseAndValidate" given mutation
* updated documentation to denote inclusiveness of ranges
* Updates for expansion of ignored inbound and outbound port ranges to be handled by the proxy-init rather than CLI (#3766)
This change maintains the configured ports and ranges as strings rather than unsigned integers, while still providing validation at the command layer.
* Bump versions for proxy-init to v1.3.0
