Draft: INT: Integration of gmresSolver from foam-extend

Summary

Integration of Foam-extend (http://www.foam-extend.org) gmres solver

Details of new models (If applicable)

• should work standalone or in combination with GAMG (with processor agglomeration)
• requires number of orthogonal directions (nDirections) as input

Risks

• will not help with scaling - no pipelining
• uses more memory (scales with nDirections)
