Support Python 3.7

[jpgxs]

From Python 3.7 async is a reserved keyword.

This causes an exception in the opsview_reload module:

Has anyone looked at this or is there any plans to fix this for newer verions of python?

Best i can tell i just changed the following in opwview_reload so that it uses the full word asynchronous and it works now.

# requires a reload
opsview_client.reload(asynchronous=True)
