added build for acctapp node
Separated the account app build from the OOD build to run as its own dedicated node. This includes creating an independent Ansible playbook (ansible/acctapp.yml) for setting up the account app node, along with necessary OpenStack Packer variable and node image files (openstack-acctapp/variables.pkr.hcl, nodeimage.pkr.hcl).
The associated roles - the acctapp role from the CRI repo, enable this build pipeline and contain account app installation and configuration steps for the account app image.
