Description

Page write throttling incorrectly calculate average checkpoint write speed in some circumstances (gets wrong interval for calculation), this leads to parking threads for too long.

Root cause: PagesWriteSpeedBasedThrottle.onMarkDirty() should not open new interval for speedCpWrite after PagesWriteSpeedBasedThrottle.onFinishCheckpoint() until new checkpoint begin.

Reproducer: PagesWriteThrottleSmokeTest.testThrottle(), currently always failed in master (https://ci.ignite.apache.org/project.html?tab=testDetails&projectId=IgniteTests24Java8&testNameId=2808794487465215609&page=1&branch_IgniteTests24Java8=%3Cdefault%3E)
