Replace hardcoded Coveo api keys with a call to Netlify function (#35)

* remove hardcoded key values, use variables instead

* update variable names to COVEO_API_*

* whitespace

* remove conditional expression for each hugo build environment

* use COVEO_SEARCH_TOKEN env var when calling js.Build

* update comment

* call Netlify function to get API key from environment

* actually call function

* use coveokey variable

* call getSearchToken() function

* remove passing search token as param to js.Build

* make entire function async

* fix path to function

* get token string

* use absolute path for search token api

* try window.location.origin as prefix for token api
