Need to parse crm_mon node attributes and pcm status for checking #health_disk and number of running resources

[Artem Hrechanychenko]

Some time need to retrieve crm node attributes to check status of some attributes and count of running resources in pcs status

Example

Node Attributes:
* Node node-3.test.domain.local:
    + #health_disk : red
    + arch : x86_64
    + cpu_cores : 2
    + cpu_info : Intel Xeon E312xx (Sandy Bridge)
    + cpu_load : 1.54,
    + cpu_speed : 4199.99
    + free_swap : 2100
    + gtid : 811ca805-741e-11e5-9c15-123a35cdc64d:351668
    + master-p_conntrackd : 100
    + master-p_rabbitmq-server : 0
    + os : Linux-3.13.0-65-generic
    + rabbit_get_alarms_timeouts : 0
    + rabbit_list_channels_timeouts : 0
    + rabbit_list_queues_timeouts : 0
    + ram_free : 950
    + ram_total : 3000
    + root_free : 0
    + var_lib_glance_free : 102400
    + var_lib_mysql_free : 19456
    + var_log_free : 7782

    Getting pacemaker node attribures and node status as dict.

    def get_pacemaker_nodes_attributes(cibadmin_status_xml)
    Adding possibility to parse 'cibadmin --query --scope status'.
    Function return nested dictionary with node-fqdn and attribute name as keys.

    def get_pcs_nodes(pcs_status_xml)
    Adding possibility to parse 'pcs status xml'.
    and return nested dictionary with node-fqdn and attribute name as keys.
    They will be used in test for pacemaker resources when disk is full
