* 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

`linkerd inject` was not checking its input for known sidecars and
initContainers.
Modify `linkerd inject` to check for existing sidecars and
initContainers, specifically, Linkerd, Istio, and Contour.
