Allow DWaveCliqueSampler to use a user specified clique embedding

[pau557]

I'm interested in using all the functionality of the clique sampler (range-scaled uniform torque compensation, per-qubit coupling checks), but I would like the option of passing my own embedding instead of generating it on the fly:

dwave-system/dwave/system/samplers/clique.py

Line 389 in 7b70235

embedding = find_clique_embedding(bqm.variables, self.target_graph,

This allows reproducibility, graph-isomorphic transformations, testing new embeddings, etc.

Definitely a feature we could (easily) add. But in the mean time you could get the same effect with just using the same set of composites

dwave-system/dwave/system/samplers/clique.py

Line 406 in 7b70235

sampler = FixedEmbeddingComposite(
