### Description of PR
When fs.azure.createRemoteFileSystemDuringInitialization is enabled, the
filesystem will create a container if it does not already exist inside the
initialize method. The current flow of creating the container will fail in the
case of concurrent initialize methods being executed simultaneously (only one
request can create the container, the rest will fail instead of moving on).
This PR is fixing this issue by also catching
org.apache.Hadoop.fs.FileAlreadyExistsException generated by the
createFilesystem command.
### How was this patch tested?
A new test in ITestAzureBlobFileSystemInitAndCreate is introduced which was
breaking before the fox.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
