This commit removes the default security group rules that are automatically
created when a security group is created. These rules are usually
permissive egress rules which makes it difficult to add more strict egress
security group rules.
This disables the computed value check for `count` during the validation
pass. This enables partial support for #3888 or #1497: as long as the
value is non-computed during the plan, complex values will work in
counts.
**Notably, this allows data source values to be present in counts!**
The "count" value can be disabled during validation safely because we
can treat it as if any field that uses `count.index` is computed for
validation. We then validate a single instance (as if `count = 1`) just
to make sure all required fields are set.
Allows the user to import a default aws_alb_listener_rule. When creating the resource with TF, the AWS API requires that `priority` be an integer.
However, the `DescribeRules` API call returns a string for `priority`. This would work in every case except for the `default` listener rule, which sets the `priority` value to the string "default".
This fixes the previous error:
```
Error importing: 1 error(s) occurred:
* aws_alb_listener_rule.test: Cannot convert rule priority %q to int: strconv.ParseInt: parsing "default": invalid syntax
```
Fixes: #11464
Previously an attempt to destroy a LB stickiness policy would
result in an error like this:
```
* aws_lb_cookie_stickiness_policy.foo: Error removing LBCookieStickinessPolicy: LoadBalancerNotFound: There is no ACTIVE Load Balancer named 'tf-test-lb-tqatd'
status code: 400, request id: 28af1167-e4a4-11e6-8ddd-57ba410cbbb6
```
This checks for a missing load balancer on the policy read and allows
the destroy.
```
