Currently, newly created `ElapsedTimeStrategy` is uninitialized and its
`hasElapsed()` has to be called once `ElapsedTimeStrategy` is created to
initialize the strategy. This is confusing and error prone.
Move initialization of `ElapsedTimeStrategy` into it's constructor, so
it's initialized once it's created.
Heartbeats should be sent when Debezium is not sending any events
obatined from the DB. Send heartbeat before finishing itteration
which doesn't contain any updates from the DB.

Lowering polling interval intorduced in previous commit doesn't fully
fix the issue and there is still small race condition. To fully fix it
add function for awaiting transaction to be propagate to CDC table and
await transaction in tests which randomly fails.
Some tests fail randomly as they insert some records at the begging
of the test, start Debezium and asserts that there are no records.
However, as SQL server poll for the changes and copies them into
CDC table not immediately but in specified interval (by default 5
secods), there can be a race condition when the entries inserted
at the beginning of the test are copied into CDC table after starting
Debezium and it resutls into the test failure as there are unexpected
records.
Add function for adjusting the polling interval and decrease polling
interval in `IncrementalSnapshotIT` which fails very often.
This doesn't fully fix the race condition, but decreases the changes
the issue is hit.
Run the tests alwyas in thr same order to make it more easy to debug
failures. If needed, the order can be changed (e.g. to `random`) by
overriding propeperty `runOrder`.
