Ocelot: Specify specific folder for config.AddOcelot()

[EdwinVW]

New Feature

I use the AddOcelot extension-method on IConfigurationBuilder to configure Ocelot in a project I'm working on. The default implementation looks in the current folder for config files and combines these into an ocelot.json file.

I would like to have the ability to specify a specific folder when using config.AddOcelot.

Motivation for New Feature

I like to define the reroutes for every API I want to publish using Ocelot in a separate config file. The new feature would enable me to have a separate folder per environment in which I can place these config files. Consider the next folder structure:

• OcelotConfig
  
  
  
  • Development
  
  
  • ocelot.global.json
  
  
  • ocelot.FirstAPI.json
  
  
  • ocelot.SecondAPI.json
  
  
  • ocelot.ThirdAPI.json
  
  
  • Production
  
  
  • ocelot.global.json
  
  
  • ocelot.FirstAPI.json
  
  
  • ocelot.SecondAPI.json
  
  
  • ocelot.ThirdAPI.json
  
  

Now I can combine all the ReRoutes specified in the separate config files for a speific environment by calling:
config.AddOcelot($"OcelotConfig\\{hostingContext.HostingEnvironment.EnvironmentName}");

Specifications

• Version: 8.0.0

Notes

In a project that I'm working on I've already added an overload of the AddOcelot extension-method on IConfigurationBuilder that accepts a folder. This works like a charm. So if this is considered a valuable addition, I can make a PR.

Another approach would be to take the Environment into consideration when traversing the config files. But this would be my second choice.

Will do. Code is complete and unit-tests are green. Will create PR shortly.
Can you assign me to the issue?
