Allow app/chewy location to be changed via yml config

[robacarp]

Hello again!

In our rails application directory we have the following folders:

assets/
contexts/
controllers/
errors/
exporters/
helpers/
jobs/
mailers/
models/
policies/
serializers/
views/

While integrating the Chewy gem, I added the app/chewy folder to the application. There were a few complaints that 'chewy' didn't match the convention applied in the app/ directory, and so I was able to change it to app/indices with a little creative monkey patching.

This patch allows the directory to be set with a new config option called index_definition_path.

I tried to find every place the path was hard coded and replace with Chewy.configuration[:index_definition_path].

Additionally, the default setting is app/chewy so current deployments shouldn't need to change anything.

Thoughts?

Thanks!

The only this here that concerns me - is the config entry name. index_definition_path is not quite clear. I would think about it. Everything else is awesome.

@pyromaniac I agree, but I couldn't come up with anything that seemed more obvious. I'm open to suggestions if you have them.

indices_path or indexes_path

[pyromaniac]

I'm not sure, which one, I can't choose :) Actually, we've got both usages all over the gem. Probably it makes sense to pick one, indices, probably. So let's use indices_path.

@pyromaniac excellent! Updated

Sorry, It looks like I fat fingered that entire commit.

Awesome, thanks!
