Added API support to add data on hawkular metrics server

[jkandasa]

With this PR we add metric data to hawkular metric service/server.

New functions:

• add_availability_feed
• add_availability_server
• add_availability_deployment
• add_gauge_server
• add_gauge_datasource
• add_counter_server
• add_counter_deployment
• add_string
• add_gauge
• add_counter
• add_availability

Usage:

from mgmtsystem.hawkular import Hawkular
from mgmtsystem.hawkular import MetricEnum
from mgmtsystem.hawkular import MetricEnumGauge
from mgmtsystem.hawkular import MetricEnumCounter
hwk = Hawkular(hostname="hawkular-service-hostname", port="8080", username="jdoe", password="password")
_data = [] 
_data.append({'timestamp': 1473782555308, 'values': 21})
hwk.metric.add_counter_deployment(feed_id='ebf0ce66-0278-4d96-b9ec-4e4d42926dbe', server_id='Local', resource_id='ExampleDS', metric_enum=MetricEnumCounter.DEP_UTM_SESSIONS_CREATED, data=_data)
