Summary0037851: Request timeout should apply to the whole process, and not just the query
DescriptionCurrently in some requests to ProcessHQLQuery masterdata classes, we receive a timeout value which we use when executing the query.

This is correct, but it's not enough: if the rest of the process (mainly, the reading of the returned data, generation of the JSON information, and writing of this JSON into the response) takes too long, the client side will already reach timeout, and all the work we do will be for nothing.

We can improve this behaviour, by measuring the time the request has already taken, and when reading the data and generating the response, checking the time and if it's gone pass the timeout, cancel the process.

This would be specially beneficial if for example some clients are having network problems, and are unable to receive the data in a reasonable amount of time. The fix would free resources in the server (bandwidth, database connections, threads) that would be otherwise consumed doing useless work, as the client has already abandoned the request because of the timeout.
Steps To ReproduceThis problem can be reproduced easily if a breakpoint is set after the query has already been executed but the response has not yet been computed.

Fixed issue 37851. Several improvements to cancel requests which are no longer needed:
- Now a 'timeToTimeout' is computed for each SecuredJSONProcess that contains a Timeout in the request information. This timeToTimeout is the instant (in number of miliseconds) in which the timeout would be reached.
- A new API, hasTimeoutBeenReached(), has been created in the SecuredJSONProcess class, which then any process can use to find out if the timeout has been reached.
- For now, this API is used in the ProcessHQLQuery class to detect in several points during the process execution if timeout was reached, and if it was, the process is then canceled.
- Also, the timeout passed to the query executed in the database has been changed, and now it takes into account the time already spent in the rest of the request. This is important because if for example the request took a significant amount of time to process (due to low network bandwidth for example), we actually have less available time to execute the rest of the process, which includes the query.

Related to issue 37851. TimeToTimeout will not be set if it is null, to prevent NPE in ExternalOrderLoader.

Related to issue 37851. Several improvements have been made:
- Now initial time is measured from the moment the request starts, instead of being measured after the request content has already been read
- Now POST requests send the timeout also as part of the URL, and is read before, so that the process can be canceled while reading the request content if it takes too much time
- Improved log message information, and removed unneeded second stacktrace
- Now checkTimeout() has been moved to SecuredJSONProcess, and it's considered the API that all processes should use
