Steffan Sluis f9fbe97509 azure: support external file dependencies (#3852) ...

* azure: support external dependencies and outputs

- Implement get_file_checksum with get_etag
- Implement a DependencyAzure and OutputAzure classes
- Add AzureOutput to OUTS, OUTS_MAP and CHECKSUMS_SCHEMA
- Add AzureDependency to DEPS and DEPS_MAP
- Add unit tests for AzureOutput and AzureDependency

Fixes #3540.

* Use content_md5 instead of etag

The etag is different for the same file in different locations.

* Use etag and remove external outputs for Azure

Due to inconsistencies with Azure's Content-MD5 property, it is not
stable enough to be used at the moment. Using the etag offers enough
reliability to support external dependencies. See also:
