The goal with this change is to persist the rate limiters across reloads with the least invasive changes possible. To do this I first added a LimiterOptions structure to hold the current set of rate limiters. I then identified each call of tollbooth.New and moved the construction of the limiter without modifications to options.go. I assigned each limiter a distinct field to be referenced during the API object creation. Next I needed to add an optional parameter to the NewAPI methods so I could store the new LimiterOptions onto the API object for reference during route construction. To do this without breaking all existing calls to NewAPI I used the options pattern. This makes the method accept a parametric set of values implementing a common interface, so future problems of similar nature can also be added as options. I then replaced all the local anonymous limiter.Limiters made inline within the API route construction with each corresponding newly added field within the LimiterOptions struct.
