Add CloudWatch to ontap monitor services

[kcantrel]

The following major changes were made:

• Added CloudWatch as an optional alert destination.
• Added an inode utilization alert at the volume level.
• Added a "filter" parameter for EMS messages so you could explicitly filter out messages as opposed to just matching them.
• Added a "match" and "exception" parameter for the volume utilization message so you could set up specific rules for particular volumes.
• Updated the README to be more accurate as to when you need to add AWS service endpoints.
• Allow you to provide an ARN for the roles so the CloudFormation template doesn't have to create them.

• [nitpick] Avoid using 'str' as a variable name since it shadows the built-in type; consider renaming it to 'timeStr' or a similar descriptive name.

str = lagTimeStr(lagSeconds)
