KustoConnectionStringBuilder does not deserialize "msi authentication" and "msi params" correctly

[creste]

Code Sample, a copy-pastable example if possible

This code:

kcsb = KustoConnectionStringBuilder.with_aad_managed_service_identity_authentication(
        connection_string=connection_string,
        client_id=client_id)
connection_string = str(kcsb)
client = KustoClient(connection_string)

Throws this exception:

KeyError: 'msi authentication'

Problem description

KustoConnectionStringBuilder serializes ValidKeywords.msi_auth and ValidKeywords.msi_params using these keys:

• MSI Authentication
• MSI Params

See:

azure-kusto-python/azure-kusto-data/azure/kusto/data/kcsb.py

Lines 33 to 34 in 5405e81

	msi_auth = "MSI Authentication"
	msi_params = "MSI Params"

When deserializing, only these keys are allowed:

• msi_auth
• msi_params

See:

azure-kusto-python/azure-kusto-data/azure/kusto/data/kcsb.py

Lines 68 to 71 in 5405e81

	if key in ["msi_auth"]:
	return cls.msi_auth
	if key in ["msi_type"]:
	return cls.msi_params

This fixes the problem:
