Allow user to request aggregating the pressure system before solving it.
...
For this we added a new parameter cpr_pressure_aggregation. If it is true
we will aggregate the pressure already for the first system.

Do not use expensive aggregation when forming pressure system unless requested.
...
That means that for traditional CPR no aggregation is used and we simply extract
the pressure component.

Use decoupling strategy of Scheichl/Masson in the CPR preconditioner.
...
Often it is claimed by CPR-AMG evangelists that this will make the pressure
system more elliptic. That may be the case. But even more important it also
decouples the pressure from the saturations.
Without this approach the pressure correction influences the smoothing of the
full system too much and e.g. for Norne CPR is worse than simple block ILU0.

First version of a AMG for the Blackoil equations.
...
The approach is inspired by Geiger's system-amg but we use dune-istl
aggregation AMG for it. On the fine level all unknowns attached to a cell
form a matrix block and are treated fully coupled. To form the first
coarse level system we use only the pressure component to guide the aggregation
and neglect all other unknowns on the fine level. All other level are formed
in the usual way by scalar aggregation.
Currently,it has to be requested for flow_ebos manually by passing
"linear_solver_use_amg=true amg_blackoil_system=true" to it.
