added a method remove_support() in beam module

[ishanaj]

The current beam module has a method apply_support() which applies a particular support on the beam and corresponding reaction force, reaction moments and boundary conditions are defined according to the type of support.

This PR incorporates a method to remove a particular support from the beam.
This would help in modifying any beam, without the need of defining it again in case of any modifications to be done on the beam or any errors made while defining a beam.

Release Notes

• physics.continuum_mechanics
  • added a method to remove previously applied support(s) on the beam.

Rest looks good to me. Let's wait for Jason to approve.

I wonder whether this is necessary. The example in the docstring is very long so I can't imagine typing it interactively. If I'm not doing it interactively then I'm doing it in a .py file and I can remove the support by deleting the line that adds the support.

That's an API design issue for the beam module though so I will defer to @moorepants.

[ishanaj]

@oscarbenjamin I guess remove_support() would have the same use case as remove_load().

[ishanaj]

@jashan498 I have corrected the errors. Could you please have a look.

@czgdp1807 I have resolved the conflicts.
I think it is ready to merge if the feature seems good to everyone.
