Description

[environment]:
OpenTelemetry collector deployed as pod in AKS
Azure AKS OS is Ubuntu Linux

[steps]:

1. when has digital 2 in azureblob.blob_name_format.logs_format, as below code.
2. There are multiple folders generated in Azure storageAccount , as below:
   cluster/test28/namespace/....
   cluster/test29/namespace/....
   cluster/test30/namespace/....
3. Actually we only has 1 cluster=test2, only cluster/test2/namespace/... is expected.
4. here front "2" in cluster/test2 is similar as latter "02" in 2006/01/02/15, it is thinked as time-format.
   the front"2" is thinked as time-format, it is NOT expected.
   the latter"2" is thinked as time-format, it is expected
5. I tried following in azureblob.blob_name_format.logs_format, the problem still exist.
   cluster/test2_test/namespace/2006/01/02/15
   cluster/test2-test/namespace/2006/01/02/15
   cluster/test2test/namespace/2006/01/02/15

    exporters:
      azureblob:
        auth:
          client_id: ***
          type: user_managed_identity
        blob_name_format:
          logs_format: cluster/test2/namespace/2006/01/02/15
        container:
          logs: backup-logs
        format: json
        url: ***

I'll create a PR to fix this issue. Actually, it's more like an enhancement. The current approach will run time.Format with whole blob name.
