 Create is an operation which provisions a new Health Monitor. There are
 different types of Monitor you can provision: PING, TCP or HTTP(S). Below
 are examples of how to create each one.

 Here is an example config struct to use when creating a PING or TCP Monitor:

 CreateOpts{Type: TypePING, Delay: 20, Timeout: 10, MaxRetries: 3}
 CreateOpts{Type: TypeTCP, Delay: 20, Timeout: 10, MaxRetries: 3}

 Here is an example config struct to use when creating a HTTP(S) Monitor:

 CreateOpts{Type: TypeHTTP, Delay: 20, Timeout: 10, MaxRetries: 3,
 HttpMethod: "HEAD", ExpectedCodes: "200", PoolID: "2c946bfc-1804-43ab-a2ff-58f6a762b505"}
