fix(sdk): making cron schedule more cloud agnostic (second attempt)

[marciocadev]

Some characters like ? are configurations used by AWS, but to make the schedule more cloud-agnostic, I made some changes to bring it closer to the Unix implementation

Now a cron like * * * * * will not throw an exception.

I removed this test because it no longer made sense.

try {
      new cloud.Schedule( cron: "* * * * *" ) as "s5";
} catch e {
      error = e;
}
assert(error == "cannot use * in both the Day-of-month and Day-of-week fields. If you use it in one, you must use ? in the other");

Closes #2849
