Let Azure Storage get_blob_properties() return part of the properties

Testing env: azure-core==1.24.0 azure-storage-blob==12.10.0 Operating System: Ubuntu, Mac OS

Azure Storage blob related APIs provide a function called get_blob_properties to return the properties of a blob. We are using it to poll a blob to check its current properties (e.g. blob size). However, we find that there is no way to define what selected property fields to return. The whole returned property dictionary is pretty big (like 1k~2k), which is not very optimized for our usage scenario. Here below is a simplest code snippet to show our usage scenario. Would you give get_blob_properties a new parameter to select the returned property fields? Like get_blob_properties(... selected_properties=['creation_time', 'size'])

from azure.storage.blob import BlobServiceClient

CONNECTION_STR = 'DefaultEndpointsProtocol=https;AccountName={};AccountKey={};EndpointSuffix=core.windows.net'
ACCOUNTNAME = 'storems365def'
ACCOUNTKEY = "************key_masked************"

CONTAINERNAME = "insights-logs-advancedhunting-emailevents"
BLOBNAME = "tenantId=8ab4b9aa-f07b-4927-a103-c20e857620a8/y=2022/m=10/d=07/h=22/m=00/PT1H.json"

blob_service_client_instance = BlobServiceClient.from_connection_string(
    CONNECTION_STR.format(ACCOUNTNAME, ACCOUNTKEY))

blob_client_instance = blob_service_client_instance.get_blob_client(
    CONTAINERNAME, BLOBNAME)

# The returned blob_properties is 1k~2k big. We need to make this call multiple times.
blob_properties = blob_client_instance.get_blob_properties()

# We only want these two fields below
print(blob_properties['size'])
print(blob_properties['creation_time'])
