These are azure specific configs name as "fs.zure.*" so not sure if it is a good idean to
add them to hadoop-common.

{{Configuration}} will load the {{core-default.xml}} file for default values in hadoop common
and tools, e.g. {{fs.s3.*}}. I also think it's a good idea to have them in {{core-defaults.xml}}
if their default values are not loaded elsewhere.

> Current implementation of WASB, only supports Azure storage keys and SAS key being provided
via org.apache.hadoop.conf.Configuration, which results in these secrets residing in the same
address space as the WASB process and providing complete access to the Azure storage account
and its containers. Added to the fact that WASB does not inherently support ACL's, WASB is
its current implementation cannot be securely used for environments like secure hadoop cluster.
This JIRA is created to add a new mode in WASB, which operates on Azure Storage SAS keys,
which can provide fine grained timed access to containers and blobs, providing a segway into
supporting WASB for secure hadoop cluster.
> More details about the issue and the proposal are provided in the design proposal document.
