We have too many different assert methods in our JavaScript end-to-end tests. The number can be reduced by generalizing some of the methods.

For instance, assert.dropExceptionsWithCode(func, dropCodes, onDrop) can be expressed through a generalized assert.doesNotThrow(func, params, ignoreErrorCodes, msg).

Another example: assert.commandWorkedOrFailedWithCode(res, errorCodeSet, msg) can be expressed through a generalized assert.commandWorked(res, msg, ignoreErrorCodes).
