> Setting fs.azure.user.agent.prefix adds customization as suffix
> eg: when I set `fs.azure.user.agent.prefix` to my email the user agent value is
> Azure Blob FS/1.0 (DBFS) (JavaJRE 1.8.0_232; Linux 4.15.0-1050-azure; SunJSSE-1.8) arunravimv@gmail.com
> I believe this is inconsistent with the similar setting in AWS S3 fs.s3a.user.agent.prefix where the customization is added as a prefix. I believe that it would be great if we make this consistent with configuration name.

> The proposed change is to fix the AbfsClient.initializeUserAgent.
>
> We use a user agent information available in cloud service logs for extended tracking.
