Description
Hi, the library currently enforces APP as a reserved keyword in connection strings https://github.com/microsoft/mssql-python/wiki/Connection-to-SQL-Database#reserved-connection-string-keywords
Is there a good reason for this? I don't see any justification in the PR https://github.com/microsoft/mssql-python/commit/8ed531e5161fbae39debf29b8e89363b1efaca31 (although there is reference to docs/connection_string_allow_list_design.md which I cannot find)
We use currently use APP internally for passing application names and find it quite useful!
