Add getter for Timeout/PollDelay/PollInterval

[asuras-coding]

Hey there,

I miss the getter methods for the configured timeouts. In our test environment, for some steps I want to increase the timeouts and later reset to the original values. Therefore it would be nice if I could use a getter to save them before changing them for a block of code

fun withAwaitilityTimeouts(
    pollDelay: Duration? = null,
    pollInterval: Duration? = null,
    timeout: Duration? = null,
    environment: Environment = Environment.LOCAL,
    block: () -> Unit
) {
    val previousPollDelay = Awaitility.getDefaultPollDelay()
    val previousPollInterval= Awaitility.getDefaultPollInterval()
    val previousTimeout = Awaitility.getDefaultTimeout()
    pollDelay?.let { Awaitility.setDefaultPollDelay(it) }
    pollInterval?.let { Awaitility.setDefaultPollInterval(it) }
    timeout?.let { Awaitility.setDefaultTimeout(it) }
    block()
    Awaitility.setDefaultPollDelay(previousPollDelay)
    Awaitility.setDefaultPollInterval(previousPollInterval)
    Awaitility.setDefaultTimeout(previousTimeout)
}
