This is just for tests since from main.go, the FlagSet is set
with ExitOnError so Parse() would call os.Exit(2).
Regardless, I wanted to add error checking and a test for that.
Related to #578
The removal of SetClientAuthMethod removed any possibility of providing
a custom auth backend.
This patch add it back as a Option attribute, so we can wait comfortably for #434,
which aims to provide more extensible external Auth.
There were some cases where override would not work. Any command
line parameter that would be set to the type default value (false
for boolean, "" for string, etc) would not be taken into account.
I moved all the flags parsing and options configuration into
a new function, which may help reduce code duplication in
NATS Streaming.
The other advantage of moving this in a function is that it
can now be unit tested.
I am also removing call to `RemoveSelfReference()` which attempted
to remove a route to self, which has been already solved at runtime
with detecting and ignoring a route to self.
This function would be invoked only when routes were defined in
the configuration file, not in the command line parameter.
Removing this call also solves an user issue (#577)

gnatsd currently uses a global logger. This can cause some problems
(especially around the config-reload work), but global variables are
also just an anti-pattern in general. The current behavior is
particularly surprising because the global logger is configured through
calls to the Server.
This addresses issue #500 by removing the global logger and making it a
field on Server.
Changing from being the number of seconds to a time.Duration.
For backward compatibility, the configuration with the number
of seconds is still accepted but an error message is printed
asking the user to convert to duration.

We use a hardcoded value of 2 seconds for Write deadline when
writing data to client's socket.
This PR makes that value configurable.
Question is should we push the setting down to the client's object
to avoid indirection such as client.srv.opts.WriteDeadline?
When a server is told to connect to a server (with auto-discovery),
it tries to connect once. There have been a report where that
connection fails, but would probably succeed if tried again (#408).
This new parameter allows to configure the number of times a failed
implicit connect should be tried.
Resolves#408
Previous implementations of the server checked the pending data size
being currently buffered for a client to detect slow consumers,
though this does not apply to latest version of the server so removing
it as a config option to avoid confusion as it is not implemented.
By default, a server is now sending to its clients the client URLs
of all servers in the cluster. This allows clients to be able
to reconnect to any server in the cluster even if those clients
were not configured with the list of servers in the cluster.
However, there may be cases where it would make sense to disable
this feature. This now can be done with this option/command line
parameter.
Resolves#322
If the server was started with a cluster section in a configuration
file and one would want to override the routes (using `-routes`) the
server would complain that you need to use `-cluster`. Adding
an override of cluster would not work, server would still complain.
Trying to override simply the cluster listen info (without override
of routes) would also not work.
