CI GH Actions structure (#112)

* Update to Nomad 0.11.3 (#96)

Addresses #84

* Fix booleans in template (#94)

nomad expects booleans in lower-case. this fixes several variables

* Update nomad to 0.12.0 (#98)

Update to nomad 0.12.0 #97

* Update nomad to v0.12.1 (#104)

Addresses #103

* Improve Vault Support for Namespace, Tokens (#102)

This adds support for Vault namespaces (from Vault Enterprise).
Additionally, this ensures that a vault token is not installed on client
nodes. Per the nomad documentation, this token only needs be installed
on servers, and tokens will be delegated appropriately to client nodes.

Addresses #101

* add parameter deployment_gc_threshold (#99)

Co-authored-by: beechesII <christopher.grau@t-systems.com>

* Feature/nomad autopilot (#100)

* add configuration for Nomad autopilot Stanza

* correct variable names

Co-authored-by: beechesII <christopher.grau@t-systems.com>

* Reference requirement for unzip

In response to #89 ...  unzip is a dependency of ansible unarchive module.

* fix cgroup-bin transition package for newer distro releases (#108)

* Fix After and Wants to start after networking (#110)

According to https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/ this is the correct way to start a service only after the network has come all the way up.
According to https://www.freedesktop.org/software/systemd/man/systemd.special.html#basic.target "systemd automatically adds dependency of the type After= for this target unit to all services (except for those with DefaultDependencies=no)", therefore having it here is redundant.

* Added configuation for podman and general plugin setups. (#111)
