Allow running persistent run hooks of all parents (#2044)

Currently, only one of the persistent pre-runs and post-runs is executed.
It is always the first one found in the parents chain, starting at this command.
Expected behavior is to execute all parents' persistent pre-runs and post-runs.

Dependent projects implemented various workarounds for this:
- manually building persistent hook chains (in every hook).
- applying some kind of monkey-patching on top of Cobra.

This change eliminates the necessity for such workarounds
by allowing to set a global variable EnableTraverseRunHooks.

By default, only the first persistent hook found in the command chain is executed.
That is why in the above output, the `rootCmd PersistentPostRun` was not called for a child command.
Set `EnableTraverseRunHooks` global variable to `true` if you want to execute all parents' persistent hooks.
## Suggestions when "unknown command" happens
Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
