Have a default hiera config that all the environments can inherit from

[davidoae]

It'd be useful if we could specify a default hiera config file that includes all the common set of options.

This can probably be achieved by adding a line in the hiera directory

:backends:
  - json
:json:
  :datadir: /etc/puppet/puppet-hilary/environments/%{::environment}/hiera
:hierarchy:
  - %{::clientcert}_hiera_secure
  - %{::clientcert}
  - %{nodetype}_hiera_secure
  - %{nodetype}
  - common_hiera_secure
  - common
  - default

Then we would add a symlink in each environment/hiera called default that is symlinked to a single file that contains all the common set of values.

Assigning to @davidoae.

Note that there might be a better way to do this using Puppet's directory environments.

Would probably be good to rename common to environment or something then too

Changing to directory environments means restructuring the manifests, seems to be a fairly large task so I've not done it for now.
I don't think 'environment' is a good replacement for 'common' as it's a term puppet uses allot.
Maybe 'base'? TBH I think common is okay.
