Add SDPAFamily to tests

[ericphanson]

Running the tests, one gets a couple of warnings due to ericphanson/SDPAFamily.jl#22.

I excluded three testsets which errored due to not returning the precise status required, and two that gave the error

 ArgumentError: Bridge of type `MathOptInterface.Bridges.Constraint.VectorFunctionizeBridge{Float64,SumOfSquares.SOSPolynomialSet{SemialgebraicSets.FullSpace,DynamicPolynomials.Monomial{true},DynamicPolynomials.MonomialVector{true},SumOfSquares.Certificate.Remainder{SumOfSquares.NonnegPolyInnerCone{SumOfSquares.DiagonallyDominantConeTriangle},PolyJuMP.MonomialBasis,Tuple{}}}}` does not support accessing the attribute `SumOfSquares.GramMatrixAttribute(1)`.

but I'm not sure if that's a problem with SDPAFamily or not. The rest for the linear and SDP tests seem to work though.

Coverage increased (+1.4%) to 77.4% when pulling 3f524f2 on ericphanson:master into 0ac73d2 on JuliaOpt:master.

Thanks for the addition. The solver tests currently don't work on SumOfSquares#master, I'm working on it, so it's expected that some tests fails. We can now add SDPAFamily in https://github.com/sums-of-squares/sos/blob/master/index.md
