[EventHubs] Remove the dependency of static resources of livetests in checkpointstoreblob

[yunhaoling]

Issue

the livetest in checkpointstoreblob(and aio) depends on static test resources: storage blob + storage blob data lake gen2
we should update to use bicep/arm template for dynamic resource creation as what we have done for other live tests.

Background

currently the livetest resource of storage blob data lake gen2 has been removed by accident.
this is a chance for us to use EnvLoadPreparer for dynamic resource creation for the checkpointstoreblob livetests:

https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/eventhub/tests.yml#L13

key points:

• azure-eventhub-checkpointstoreblob is using storage blob and storage blob gen2 datelake (it's different than normal storage blob) for live tests.
• for storage blob, confirm livetest for checkpointstoreblob is using dynamic resources, if not then we should move to the dynamic approach (EnvLoader)
• for storage blob gen2 datelake, it's currently skipped in livetest

Goal

• use EnvLoader to dynamically create test resources for checkpointstoreblob related test
  • normal storage blob
  • storage blob gen2 datelake
