tools: Convert ndnsec to v2::KeyChain

This commit removes the following tools:
- cert-revoke (wasn't working properly before and need a new
  design)
- set-acl (wasn't working before)
- dsk-gen (no longer makes sense with the new certificate naming
  conventions, new tools for creating derivative certificates will
  be created later)

This commit also fixes Bug #3644 causing import command to ask for
unnecessary password confirmation.

ndnsec main now catch all exceptions logs the extended message
