How can use init script stored in workspace which copies jar from storage account and put it inside /databricks/jars location. 

As said in init_script migration document, where your init scripts are “self-contained,” i.e., DO NOT reference other files such as libraries, configuration files, or shell scripts. We highly recommend storing init scripts as
workspace files. But as our init script references the jar file I want to migrate it to storage account.

I am using Databricks LTS 10.2 version. Currently we were storing jar in /dbfs/Filestore/tables location and then moving it to /databricks/jars location. But as the dbfs mounts are going to be deprecated, I want to store jar in storage account and copy it into  /databricks/jars location. Please suggest.
