New function for getting a full summary of agents

[druizz90]

Hi team,

This endpoint is for giving support in framework to #429. A new endpoint was required in 426 and this PR gives support to it:

A unit test was added too:

@patch('wazuh.common.database_path_global', new=os.path.join(test_data_path, 'var', 'db', 'global.db'))
@patch('wazuh.agent.Agent.get_all_groups')
def test_get_full_summary(mock_get_all_groups, test_data):
    """Test get_full_sumary method."""
    expected_keys = {'unique_node_names', 'groups', 'unique_agent_os',
                     'summary', 'unique_agent_version', 'last_registered_agent'}
    result = Agent.get_full_summary()
    # check keys of result
    assert(set(result.keys()) == expected_keys)

All unit tests work:
