Need a feature where we can pull the private key directly from os.environ["SNOWFLAKE_PRIVATE_KEY"], instead of having an option where it should be in a file only.

Is your feature request related to a problem? Please describe. Sometimes we don't want to store the keys in file and we directly want to use them. Current implementation, doesn't allows it.

Describe the solution you'd like we can pull the private key directly from os.environ["SNOWFLAKE_PRIVATE_KEY"]

elif os.getenv("SNOWFLAKE_PRIVATE_KEY"):
    SF_PK = os.environ["SNOWFLAKE_PRIVATE_KEY"]

    key = str.encode(SF_PKB)

    with BytesIO(key) as pp_key:
        p_key = serialization.load_pem_private_key(
            pp_key.read(), password=None, backend=default_backend()
        )

    pkb = p_key.private_bytes(
                encoding = serialization.Encoding.DER,
                format = serialization.PrivateFormat.PKCS8,
                encryption_algorithm = serialization.NoEncryption())

    self.conArgs['private_key'] = pkb
