The default font in Windows console did not support the Unicode
characters recently added to check and inject commands. Also the color
library the linkerd cli depends on was not being used in a
cross-platform way.
Replace the existing Unicode characters used in `check` and `inject`
with characters available in most fonts, including Windows console.
Similarly replace the spinner used in `check` with one that uses
characters available in most fonts.
Modify `check` and `inject` to use `color.Output` and `color.Error`,
which wrap `os.Stdout` and `os.Stderr`, and perform special
tranformations when on Windows.
Add a `--no-color` option to `linkerd logs`. While stern uses the same
color library that `check`/`inject` use, it is not yet using the
`color.Output` API for Windows support. That issue is tracked at:

* When injecting, perform an uninject as a first step
Fixes#1970
The fixture `inject_emojivoto_already_injected.input.yml` is no longer
rejected, so I created the corresponding golden file.
Note that we'll still forbid injection over resources already injected
with third party meshes (Istio, Contour), so now we have
`HasExisting3rdPartySidecars()` to detect that.
* Generalize HasExistingSidecars() to cater for both the auto-injector and
* Convert `linkerd uninject` result format to the one used in `linkerd inject`.
* More updates to the uninject reports. Revert changes to the HasExistingSidecars func.

The outputs of the `check` and `inject` commands did not vary much
between successful and failed executions, and were a bit verbose and
challenging to parse.
Reorganize output of `check` and `inject` commands, to provide more
output when errors occur, and less output when successful.
Specific changes:
`linkerd check`
- visually group checks by category
- introduce `hintURL`'s, to provide doc links when checks fail
- add spinners when retrying, remove additional retry lines
- colored unicode characters to indicate success/warning/failure
`linkerd inject`
- modify default output to mirror `kubectl apply`
- only output non-successful inject reports
- support `--verbose` flag to output all inject reports
Fixes#1471, #1653, #1656, #1739
