/member/my-sessions - Add user confirmation when clicking on 'Withdraw'

It would be a good idea to add a user confirmation after clicking the 'Withdraw' link on the sessions page. While the user can edit a withdrawn session and submit again, a user confirmation on the original request would confirm that this is what they really wanted to do.

@mcookWI do you have an example of anywhere else a confirmation modal is being used in the project? Would enjoy tackling this but want to do it the "approved" way :P thanks!

@joshpierce I do not believe we are using anywhere else, but am confirming.

@joshpierce We are not currently using this anywhere else in the project. Go ahead and tackle away! :)
