trocla_lookup a hierarchy key with dots

[arlt]

We have hiera databases inside /etc/puppet and outside. So the trocla_hierarchy path can have dots.

:hierarchy:
  - "../../hieradb/nodes/%{::hostname}"
  - ../../hieradb/common
  - common

We create a password with "%{hiera('trocla_hierarchy::plain::test')}" for the puppet node "xyz".

Result:

  hiera/../../hieradb/nodes/xyz/test: 
    plain: "BNl6M_anzJRBx6WS"

We try to access the passwords with "%{hiera('trocla_lookup::plain::hiera/../../hieradb/nodes/xyz/test')}".

As a result we get this additional entry in trocla.yaml (key has the dots removed):

  hiera/hieradb/nodes/xyz/test: 
    plain: "c4j(/z9[sgjDNj34"

With trocla get 'hiera/../../hieradb/nodes/xyz/test' plain we get the expected password.

Sometimes (i don't know when/why), the key (for the lookup with dots) is created like this:

  hiera/: 
    plain: ...

The password which i receive in puppet is empty ("").

I changed :datadir: from /etc/puppet/hieradb to /etc. So ../../ in hierarchy: is not needed anymore.
This is my solution. It's still an issue but in my opinion, you can close it because the result without ../../ looks better, too.
