Add data source snowflake_current_account

[robbruce]

Creates a new data source snowflake_current_account which allows the account information to be read and then passed into other systems as part of a terraform deployment.

This avoids having to pass in the same information as variables to terraform and can use the information supplied by the provider.

I didn't know this function existed 😅
