Adding Swagger example files for all of ADLA and ADLS (Azure#1418)

* Make readOnly properties readOnly

* Translation of master -> current for ADL

This takes all of the new x-ms-examples from PR:
* begoldsm#9

And puts them into the correct format for the new branch structure.

* Fix pathing and add newlines

Added new lines to the end of all example files to make GitHub happy.
Fixed the ../examples to be ./examples due to the new folder structure.

* Undoing readOnly change for this PR

Current PR is focused only on adding examples. I will make functional
updates to the spec in a separate branch.

* Fixes to specs due to missing requirements

Fixed query params and moved one operation back into "paths" due to
missing requirements documented in this github issue:
Azure/autorest#2440

* Update examples to include OP now.

* Fix a couple validation issues

1. copy paste fail for LISTSTATUS
2. A change that should be in a different branch ended up in this PR.
Reverted it (for the account_list payload).

* Fix validation error because exception is required.

* Missed the x-ms-azure-resource tag
