OPTION to disable auto transaction creation

[Legion112]

Is your feature request related to a problem? Please describe.
I wanna user custom transaction creation with naming offered by framework.
There is a way to disable auto transaction creation for HTTP request via transaction_ignore_urls but there is no way to do same for cli command.

Describe the solution you'd like
Would be nice to have a single option that disables entirely auto transaction creation like transaction_auto which would have default value to true

Changes have to be made inside here:

apm-agent-php/agent/php/ElasticApm/Impl/AutoInstrument/TransactionForExtensionRequest.php

Lines 123 to 125 in 85b17c0

	private function beginTransaction(float $requestInitStartTime): ?TransactionInterface
	{
	if (!self::isCliScript()) {

Before executing this method we should check if it is allowed to created transaction automatically via setting (transaction_auto)

You can achieve your goal using public API ElasticApm::getCurrentTransaction()->discard().
