Fix break in MSI Auth

FIXES:

• MSI auth throws exception due to change in token result format

Graduate Kusto Python to Version 1.0.0

This release include some miscellaneous changes and features.

BREAKING CHANGES:

• Authentication via Managed Service Identity uses azure.identity instead of msrestazure.
  This library caches tokens which would resolve some issues for high capacity users.
  At the moment however, it only supports obtaining user managed service identities via the client_id hint.
  Attempting to provide KustoConnectionStringBuilder with an object_id or msi_res_id will result in a ValueError exception being thrown.

FEATURES:

• Added an option to authenticate using a certificate subject name and issuer.
  KustoConnectionStringBuilder.with_aad_application_certificate_sni_authentication(cluster, client_id, PEM, public_certificate, thumbprint, authority_id)

FIXES:

• Fix a bug where the exception text description reported to KustoServiceError were not saved due to a change in the syntax for explicitly calling a Super class constructor. Please mind that,
  -- The exception text description is saved in the args field of the Exception class.
  -- The message field no long exists in Python 3

• Raise descriptive exception when az cli token not found when using az cli authentication.

Support Blob Storage API 12.x.x

Release is mostly around changing the dependency for Azure Storage on the azure-kusto-ingest package.

It also includes various changes, which are mostly cosmetic, as well as adding E2E tests and adding them to the build pipeline as a check.

BREAKING CHANGES:

• Upgraded to use Azure Storage v12 (will require dependencies)
• All arguments changed to snake_case to conform to python guidelines.
• Renamed azure.kusto.data.request to azure.kusto.data.client - old import of from azure.kusto.data.request import KustoClient will now break. should change them to `rom azure.kusto.data import KustoClient

FEATURES:

None

FIXES:

• fixed breaking test (test_kusto_streaming_ingest_client.py)

OTHERS:

• Etoe tests - cleanup, grabbing connection parameters from env, and running inside buildpipeline.
• Added Contrib doc
• Added annotations where possible

Various minor fixes

BREAKING CHANGES:

• None

FEATURES:

• New option to authenticate by providing a function callback to KustoConnectionStringBuilder which returns a valid authentication token as a string, e.g.

token_provider = lambda: "{caller token}"
kcsb = KustoConnectionStringBuilder.with_token_provider("http://mykusto.kusto.windows.net", token_provider)

• When ingesting zip and gzip files, and uncompressed file size is not provided by the caller, attempt to detect uncompressed size from the file metadata.

• When ingesting, a user can provide inline ingestion mapping in the ingestion command instead of creating it in advance.
  We suggest to use the new columnMapping class instead of CsvColumnMapping or JsonColumnMapping.

FIXES:

• When ingesting a file and uncompressed file size is provided by the caller, use provided uncompressed file size instead of estimating the uncompressed size from the file size or file metadata
