Created initial (incomplete) logging of timings for generic popping from container.

session finished" cta-taped log messages always be on the end.

Set default to 8k as seen in this documentation:
http://www.rsyslog.com/doc/v8-stable/configuration/global/index.html.

As agreed by Eric and Steve, the "<priority | LOG_LOCAL3>" prefix
of non-syslog error messages has been dropped.

All sub-classes of the Logger class, excluding DummyLogger and
SysLogLogger, now prefix each log message with the same header
as CASTOR.

Please note that SysLogLogger class intentionally leaves the
creation of log message headers to rsyslog.  It is the
responsibility of the system administrator/operator to configure
rsyslog to generate the header syntax they wish including the
precision of the timestamp within the header.

I have removed the generation and formating of timestamps from
the CTA logging system.

The log line creation function Logger::writeLogMsg does not add the trailing newine.
Instead, the overloads of reducedSyslog() do, il needed and after possible line truncation.

The logs parameters strcuture is reused for several session in the main process.
They are now cleared after the last log for a given session.

Remove debug printouts as the previous commit solves the race condition in CI we were investigating.

Enabled string logger printout to better understand intermittent failures in continuous integration.

Completed changes so that archive and retrieves can be queued, mounts created and jobs reported done.

The contents of the Utils.cpp file is a namespace and not a class
therefore the file should start with a lower case letter.

Created an StdoutLogger class.
Created a CommandLineParams class that will allow early parsing, before the daemon object is actually created.

Removed unused cmake directory.
Added missing reset to getopt's global variables.
Fixed missing inclusion of unit test.
Fixed code that failed in unit tests.
