Update Sample Apps aws-sdk-call param name to indicate Test ID

[jj22ee]

Issue #, if available:
Followup on #7
In the future, when new metric rollup tests are added for aws-sdk-call, the S3 bucket name will have the workflow Testing ID appended to it, not the IP.

Description of changes:
Rename parameter ip to testingId for aws-sdk-call endpoint in each sample app

Testing:
Python and Java updated sample apps were uploaded to personal AWS account's S3 and ECR to be used in the following test runs:

Also, make sure any calls made to /aws-sdk-call also either do not use this (as it should be optional) or provide the testing ID as the appended value

[jj22ee]

The testing done indicates that these parameters are indeed optional as testingId is not used in the tests.
