Add a hold parameter for symbolic integrals

[sagetrac-tmonteil]

As discussed in this ask question, there is no hold parameter for integration:

sage: integral(x^2, x, 0, 3, hold=True)
TypeError: integrate() got an unexpected keyword argument 'hold'

However definite_integral and indefinite_integral support this paramter:

sage: from sage.symbolic.integration.integral import definite_integral
sage: definite_integral(x^2, x, 0, 3, hold=True)
integrate(x^2, x, 0, 3)
sage: latex(_)
\int_{0}^{3} x^{2}\,{d x}

Since integral basically calls the previous functions, we should transfer this parameter.
