Description: # Openstack Nova HA monitor package
        
        Openstack Nova HA monitor is monitoring state of ocmpute nodes and when any of them fails it
        will initial compute node takeover on HA node.
        
        ## Documentation
        
        ### Consul K/V store values
        
        _ha_cluster/compute_nodes/{{ compute-node }}/status/failed_
            - fail status of the compute node, if this is set to true, this node is considered failed,
              and will be recovered. If this status becomes "True" it can only be reset to "False"
              manually by Administrator.
        _ha_cluster/compute_nodes/{{ compute-node }}/status/recovered_
            - this value is becomes True, once HA node attempts to recover this node. HA nodes only
              try to recover nodes which have "status/failed" set to True and "status/recovered"
              set to "False". Once this becomes True, only andministrator can set it back to False
        _ha_cluster/compute_nodes/{{ compute-node }}/internal/number_fails_
            - counter of HA Monitor check interval failures. HA Monitor periodically checks
              health of compute node, and increases this counter. When this counter reaches defined
              threshold, the HA Monitor sets "status/failed" to True.
        _ha_cluster/compute_nodes/{{ compute-node }}/internal/runtime_config_
            - runtime local config of the compute node. This config contains all
              required information for performing the recovery.
        _ha_cluster/compute_nodes/{{ compute-node }}/config/bmc/user_
            - ilo/ipmi user name used to managed this compute-node remotely
        _ha_cluster/compute_nodes/{{ compute-node }}/config/bmc/password_
            - ilo/ipmi user password used to managed this compute-node remotely
        _ha_cluster/compute_nodes/{{ compute-node }}/config/bmc/ip_
            - ilo/ipmi ip address used to managed this compute-node remotely
        _ha_cluster/compute_nodes/{{ compute-node }}/config/ssh/user_
            - ssh-check required test user login
        _ha_cluster/compute_nodes/{{ compute-node }}/config/ssh/password_
            - ssh-check required test user password
        _ha_cluster/compute_nodes/{{ compute-node }}/general_
            - empty directory for now
        
        _ha_cluster/ha_nodes/{{ ha-node }}/status/in_use_
            - When HA Node starts recovering a compute node, it marks it sets this value to True,
              to prevent condition where two compute nodes fail at the same time and HA Node tries
              to recover both simultaneously. Updating of this value is in critical section.
        _ha_cluster/ha_nodes/{{ ha-node }}/general_
            - empty directory for now
        
        ## Development
        
        ### Running unit tests
        
        ```console
        pytest -v -s
        ```
        
        ### Running integration tests
        
        Integration tests are implemented in `tests/integration` directory. They are based on vagrant which will start 2 VMs w
        
        
        # TODO
        
        1) Split Consul based cluster monitor from NOVA HA recovery part.
        
        2) Create integration tests.
