I barely have any file valled "vault.ini" or "vault.yml" except of in
the ansible context. So, this treat all these files as ansible-vault
files. The other change affects the way we're looking for an ansible.cfg
file. 1st we check if it's present in the current working dir, if it's
missing there we check if one exists in the same directory as the
vault-file itself. If we do not find any files then we give up and do
not decrypt/encrypt the vault-file. Note, that this also means that we
need an ansible.cfg for the vault to be encrypted/decrypted, no other
method is implemented.
