Without this change the "Import variables specific to distribution"
tasks fail with "Could not find file on the Ansible Controller..."
on environments with inject facts disabled.
This changes the tests to run with ansible with
inject_facts_as_vars = false and fixes other roles and playbooks.
There are some issues using a combination of `lookup('file')` and the
`b64encode` filter in Ansible, making tests unstable. This change
removes the usage of b64encode when loading public and private keys
from files in the Vault test playbooks.
The file lookup is by default setting `rstrip=True` which could lead
into a stripped new line. This is not happening always but resulted in
failed tests sometimes with certificates pasted to the b64encode filter.
For calls of lookup in the certificae tests `rstrip=False` has been
added to make sure that this is not happening any more. Not in
test_dnsrecord as lookup(..., rstrip=False) is adding a new line if
there was not a new line and this is an issue for dnsrecord. The user
and host tests have also been simplified to create the base64 encoded
file in the beginning and use this file then later on in the tests
without the need to use the b64encode filter.

This change split vault tests in several files, organized by vault
type and operation (vault vs. member) so that it is easier to add
new tests for issues and verify if tests are missing.
