Fail build when incremental task does not declare outputs

#9723

Address review feedback

Deprecate declaring incremental tasks with no outputs

An incremental task should always declare an output. Gradle

automatically declared an upToDate spec for incremental tasks to make

sure this is always the case.

Actually, the implementor of the task should add the spec if the task

does not declare any outputs. We expect nearly all incremental tasks

to already declare outputs.

Changed a bunch of integration tests to use the various task assertion methods instead of directly querying the `executedTasks` and `skippedTasks` collections. These methods can give better diagnostics when the assertion fails, and can perform additional checks.

Change `ExecutionResult` so that it does not ignore `buildSrc` tasks.

Let integration tests in 'core' not use deprecated configurations

On CI redirect maven central queries to local repo for integration tests

Removed some cases of messing with file timestamps in tests. These should not be required any more.

Removed trace from int tests.

Merge branch 'release'

Added some trace to int test.

Fix flakiness of TaskTypeUpToDateIntegrationTest

My theory is that the second run of the copy task after the

change was not up to date (that was the error reported in the

flaky tests) since when snapshotting the task outputs after the

second copy task given that the old output has been there before

the cache thinks that we do not need to snapshot since less a

second passed since the output file has been created. Then

we would record the output file with the state at the beginning

of the copy task and the second run would then mark it as

out of date since the output changed.

Fix flakiness of TaskTypeUpToDateIntegrationTest

We fail to discover sub second modification times for files.

Make sure the changed files have at least two seconds difference

in modification time.

Added some int test coverage for incremental build.

Add separate test for GRADLE-2936

Link previous test to GRADLE-1910
