As we add more entries and some of them has non trivial processing it seems
useful to make the processing leaner and clearly separated to simplify futures

Start gpg-agent, which is required by GnuPG v2

#if gpg21
  $ gpg-connect-agent -q --subst /serverpid '/echo ${get serverpid}' /bye \

and migrate secret keys

#if gpg2
