No writing permission to /vendor/ folder for log file creation

[kaurov]

Problem:
To get response code from server, it is required to enable debugging.
If to enable debugging then log file is located in
./vendor/snowplow/snowplow-tracker/debug/sync-events-log-6626efcd69d653.43454099.log
it is hard-coded in \Snowplow\Tracker\Emitter::initDebugLogFiles()

Some web-script keeps this folder without writing permission.
There is a need to be able to configure log file location in constructor

Attempt to work around -- failed
To do it in 2 steps

$emitter = new SyncEmitter(static::COLLECTOR_HOST, "https", "POST", 1, false, 3);
$emitter ->setup('/../../../../../../../../../htdocs/uploads/prefix', true, 3);

This way I get no error on writing permission, but http requests are not sent to remote server.

Work around
Declare debug mode in constructor and catch clear screen output

ob_start();
$emitter = new SyncEmitter("collector-endpoint.somedomain.com", "https", "POST", 1, false);
...
ob_end_clean();

Ideal solution

• To be able to configure log file location in constructor.
• To be able to configure log file location in $emitter ->setup()method without causing all request mocked -- not sent to remote server
• To be able to disable logging in file as well -- e.g. I am using only returned array.
• To be able to disable var_dumps to screen -- e.g. to use $output object or to have 2 modes -- 1) return server responses only 2) real debugging with output
