Motivation

The pyinstaller build needs some changes to work with the new standalone cli. The old build referenced localstack_ext and localstack.pro.core modules that no longer exist in the new localstack_cli namespace.

Changes

• Change main.py entry point to import localstack_cli
• Update Makefile pyinstaller arguments to use localstack_cli
• Remove references to localstack_ext and localstack.pro.core
• Replace hooks/hook-localstack_core.py with hooks/hook-localstack.py
