## Changes
Enable errcheck linter for the whole codebase.
Fix remaining complaints:
- If we can propagate error to caller, do that
- If we writing to stdout, continue ignoring errors (to avoid crashing
in "cli | head" case)
- Add exception for cobra non-critical API such as
MarkHidden/MarkDeprecated/RegisterFlagCompletionFunc. This keeps current
code and behaviour, to be decided later if we want to change this.
- Continue ignoring errors where that is desired behaviour (e.g.
git.loadConfig).
- Continue ignoring errors where panicking seems riskier than ignoring
the error.
- Annotate cases in libs/dyn with //nolint:errcheck - to be addressed
later.
Note, this PR is not meant to come up with the best strategy for each
case, but to be a relative safe change to enable errcheck linter.
## Tests
Existing tests.
## Changes
`os.Getenv(..)` is not friendly with `libs/env`. This PR makes the
relevant changes to places where we need to read user home directory.
## Tests
Mainly done in https://github.com/databricks/cli/pull/914
