Support creation of vendor-specific versions of the fabric pipeconf
We provide a new service to facilitate registration of vendor-specific
versions of the Fabric pipeconf (e.g., for Tofino) from third-party
apps. This service is designed such that third-party apps do not need to
depend on internal classes at compile time, such as the behaviour
implementations.
To make this possible, the package structure has been refactored to
separate APIs from implementation.
