Dynamically Reload Map

nginx parses configuration as a whole, either on start or on HUP signal.

Your map is part of the configuration (separating it in multiple files does
not change the fast everything is being merged before being statically
interpreted/compiled), thus you need to signal the master process whenever
you change it.

nginx gracefully finishes processing current requests on old workers while
spawning new ones and accepting new connections there.
If performance is an issue, I suggest you have a serious look at how you
dimensioned your infrastructure, since max the double of workers could use
resources at the same time.
If not, you will then have to resort to killing old workers manually.
