The existing hint URLs printing by `linkerd check` pointed to locations
that would change if the linkerd.io website was reorganized.
linkerd/website#148 introduces an alias for hint URLs at
https://linkerd.io/checks/. This is the corresponding change to update
`linkerd check` output.
Depends on linkerd/website#148, relates to linkerd/website#146.

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:

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
