> Issue Type: Bug
> Components: fs/azure

> *Bug description:*
> 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 is happen due to the `checkException` method that
> is not catching the Hadoop `FileAlreadyExists` exception.
> Stacktrace:
> {{Caused by: org.apache.hadoop.fs.FileAlreadyExistsException: Operation
> failed: "The specified filesystem already exists.", 409, PUT,
> https://<REDACTED>.dfs.core.windows.net/project?resource=filesystem,
> FilesystemAlreadyExists, "The specified filesystem already exists.
> RequestId:<REDACTED> Time:2021-10-18T13:46:05.7504906Z"}}

> org.apache.hadoop.fs.azurebfs.AzureBlobFileSystem.checkException(AzureBlobFileSystem.java:1182)}}}}
> {{ {{at
> org.apache.hadoop.fs.azurebfs.AzureBlobFileSystem.createFileSystem(AzureBlobFileSystem.java:1067)}}}}
> {{ {{at
> org.apache.hadoop.fs.azurebfs.AzureBlobFileSystem.initialize(AzureBlobFileSystem.java:126)}}}}
> {{ {{at
> org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2669)}}}}
> *To reproduce:*
> * Set `fs.azure.createRemoteFileSystemDuringInitialization` to `true`
> * Run two concurrent `initialize` commands with the root to the non existing
> container/filesystem.

> *Proposed fix:*
