Do not ignore permission errors in kopia restore command

[TimonOmsk]

Change Overview

By default kopia ignores all the errors about permissions (see https://github.com/kopia/kopia/blob/master/cli/command_restore.go#L144)
It leads to hiding such errors and incorrectly restored apps without any notifications.

I'd like @pavannd1 or someone else from his team to approve to make sure that they are aware of it and potential implications it can bring.
Probably we should not hardcode it in kanister but propagate --ignore-permission-errors flag value from k10 to avoid any issues for external kanister users.

The only doubts I have is about using strconv in commands. Maybe it would be better to create AppendLoggableKVBool function and convert from bool to string in that function and not in command? @pavannd1 @pchistikov
