Add new CloudWatchKeywords
Add new session keyword: "Create Session With Role"
Add new dynamo keyword: "Dynamo Update Key"
Add new S3 keywords: "S3 Get File Content", "S3 Get File Metadata" and "S3 Copy Between Buckets"
In the cases that is need to inform the endpoint_url (like testing in localstack) insted in pass this argument in every keyword like before, I created the "CloudWatch Set Endpoint Url", "S3 Set Endpoint Url" and "Dynamo Set Endpoint Url" this will set the endpoint_url for all keywords of the service.
