This commit deprecates the BIPMapping transpiler pass. Since its introduction the pass has been in a weird state since it's introduction. It is a standalone transpiler pass that we never integrated it into transpile() because it has an external dependency on cplex which is a proprietary software package that most people don't have access too. With the introduction of the transpiler stage plugin interface the pass has been turned into an external package: https://github.com/qiskit-community/qiskit-bip-mapper By using the plugin interface the pass can now be cleanly integrates into the transpile() function and also makes the requirement to have cplex installed much more explicit. For users with cplex it's much easier to run the BIPMapping pass as part of a transpilation workflow with `transpile(..., routing_method="bip")`. Closes Qiskit#8662

Summary
This commit deprecates the BIPMapping transpiler pass. Since its introduction the pass has been in a weird state since it's introduction. It is a standalone transpiler pass that we never integrated it into transpile() because it has an external dependency on cplex which is a proprietary software package that most people don't have access too. With the introduction of the transpiler stage plugin interface the pass has been turned into an external package:
https://github.com/qiskit-community/qiskit-bip-mapper
By using the plugin interface the pass can now be cleanly integrates into the transpile() function and also makes the requirement to have cplex installed much more explicit. For users with cplex it's much easier to run the BIPMapping pass as part of a transpilation workflow with
transpile(..., routing_method="bip").Details and comments
