- Add Go 1.17
- Fix go fmt from Go 1.17 (build directives)
- Download version of misspell and staticcheck instead of doing
"go get" since current staticcheck would be broken without go.mod

Currently in tests, we have calls to os.Remove and os.RemoveAll where we
don't check the returned error. This hides useful error messages when
tests fail to run, such as "too many open files".
This change checks for more filesystem related errors and calls t.Fatal
if there is an error.
Currently, temporary test files and directories are written in lots of
different paths within the OS's temp dir. This makes it hard to know
which files are from nats-server and which are unrelated. This in turn
makes it hard to clean up nats-server test files.
- All writes will now be done by the writeLoop, unless when the
writeLoop has not been started yet (likely in connection init).
- Slow consumers for non CLIENT connections will be reported but
not failed. The idea is that routes, gateway, etc.. connections
should stay connected as much as possible. However if a flush
operation times out and no data at all has been written, the
connection will be closed (regardless of type).
- Slow consumers due to max pending is only for CLIENT connections.
This allows sending of SUBs through routes, etc.. to not have
to be chunked.
- The backpressure to CLIENT connections is increased (up to 1sec)
based on the sub's connection pending bytes level.
- Connection is flushed on close from the writeLoop as to not block
the "fast path".
Some tests have been fixed and adapted since now closeConnection()
is not flushing/closing/removing connection in place.

Allow auto-rotation of log files when the size is greater than
configured limit.
The backup files have the same name than the original log file
name with the following suffix:
<log name>.yyyy.mm.dd.hh.mm.ss.micros
where:
- yyyy is the year
- mm is the month
- dd is the day
- hh is the hour
- mm is the minute
- ss is the second
- micros is the number of microseconds (to help avoid duplicates)

Running test suite on a Windows VM, I notice several failures.
Updated the compute of the RTT to be at least 1ns. I think that
this is just an issue with the VM I am running, but that change
will have no impact for normal situations (since setting the rtt
to the very minimum duration (1ns) instead of 0) and will prevent
some tests from failing.
Because of those same timer granularity issues, I had to add some
delays between some actions in order for time.Sub()/Since() to
actually report something more than 0.

for the process name and service name. This allows the reuse of this
code in NATS Streaming Server by invoking the new setters to
change the service and process names.

The use of the `svc` API prevented the NATS Server to run as
a container on both nanoserver and windowsservercore Docker images.
An attempt was made to replace svc.Debug with normal server.Start()
if detected to be interactive, however, that did not work. The
fact of detecting if interactive or not already requires connecting
to the service controller apparently.
This change looks up for an environment variable (NATS_DOCKERIZED)
and if set to "1", will not make use of the `svc` package.
This environment variable will be set in the Docker image (in
nats-docker/windows/nanoserver/Dockerfile and windowsservercore/Dockerfile).

Govet doesn't like functions that look like format handlers not ending in `f`,
such as Debug() vs Debugf(). This is changing some of the new log handling to
use 'f' function names to appease govet.
Updated the implicit handling of including the client as an arg without being
used in a format string. Now the client object simply has a Errorf function
for logging errors and it adds itself onto the format string.
