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

Using `/bin/env` increases portability for the shell scripts (and often using `/bin/env` is requested by e.g. Mac users). This would also facilitate testing scripts with different Bash versions via the Bash containers, as they have bash in `/usr/local` and not `/bin`. Using `/bin/env`, there is no need to change the script when testing. (I assume the latter was behind c301ea214b (diff-ecec5e3a811f60bc2739019004fa35b0), which would not happen using `/bin/env`.)

- Add quotes where missing, to handle whitespace & c:o.
- Use single quotes for non-expansion strings.
- Fix quotes were the current would cause errors.

Here we upgrade our dependencies on client-go to 0.17.4 and smi-sdk-go to 0.3.0. Since smi-sdk-go uses client-go 0.17.4, these upgrades must be performed simultaneously.
This also requires simultaneously upgrading our dependency on linkerd/stern to a SHA which also uses client-go 0.17.4. This keeps all of our transitive dependencies synchronized on one version of client-go.
This ALSO requires updating our codegen scripts to use the 0.17.4 version of code-generator and running it to generate 0.17.4 compatible generated code. I took this opportunity to update our code generation script to properly use the version of code-generater from `go.mod` rather than a hardcoded SHA.

* Fix whitespace path handling in non-docker (build) scripts
Handling of whitespace paths was not fully implemented; this patch adds
the missing pieces. Also, only use bash where bash-specific
functionality is used/needed.

The repo relied on `dep` for managing Go dependencies. Go 1.11 shipped
with Go modules support. Go 1.13 will be released in August 2019 with
module support enabled by default, deprecating GOPATH.
This change replaces `dep` with Go modules for dependency management.
All scripts, including Docker builds and ci, should work without any dev
environment changes.
To execute `go` commands directly during development, do one of the
following:
1. clone this repo outside of `GOPATH`; or
2. run `export GO111MODULE=on`
Summary of changes:
- Docker build scripts and ci set `-mod=readonly`, to ensure
dependencies defined in `go.mod` are exactly what is used for the
builds.
- Dependency updates to `go.mod` are accomplished by running
`go build` and `go test` directly.
- `bin/go-run`, `bin/build-cli-bin`, and `bin/test-run` set
`GO111MODULE=on`, permitting usage inside and outside of GOPATH.
- `gcr.io/linkerd-io/go-deps` tags hashed from `go.mod`.
- `bin/update-codegen.sh` still requires running from GOPATH,
instructions added to BUILD.md.

The openAPIV3Schema validation in the ServiceProfiles CRD is very limited in what it can validate and is obviated by more sophisticated validation done by the validating admission controller. Therefore, we would like to remove the openAPIV3Schema validation to reduce the size and complexity of the CRD object.
To do so, we must also bump the version of the ServiceProfile custom resource from v1alpha1 to v1alpha2. This ensures that when the controller is upgraded, it will attempt to watch the v1alpha2 resource. If it cannot (because, for example, the controller pod started before the ServiceProfile CRD was updated and therefore the v1alpha2 version does not exist) then it will go into a crash loop backoff until it can. This essentially means that the controller will wait for the CRD to be upgraded to include v1alpha2 before it will start.
Bumping the version is necessary because if we did not, it would be possible for the controller to start before the CRD is updated (removing the validation). In this case, when the CRD is edited, the controller will lose its list watch on ServiceProfiles and will stop getting updates.

To support reading and writing of the ServiceProfile custom resource, we add a codegen'd Kubernetes client for this resource.
* Adding the ServiceProfile type and related boilerplate to /controller/gen/apis/serviceprofile. This boilerplate also contains directives that control how codegen works.
* A script in /hack which invokes codegen that generates Kubernetes client machinery for interacting with ServiceProfile resources. The majority of the generated code lives in /controller/gen/client.
* The above-mentioned generated code.
