Add custom permission for administering the module

Hey guys,
Currently working on this. Will post a patch soon

Hi guys,

Attached a Patch for this. Please have a look

Sorry guys, ignore the last patch. Please see below snippet

We need to create flexible_google_cse.permissions.yml file in the module root folder. Place the below code

administer google_cse permission:
  title: 'Administer Google CSE'
  description: 'Allow access to google custom search engine'

Then in routing.yml file, add this custom permission

flexible_google_cse.flexible_search_controller_search:
  path: '/fgs-search'
  defaults:
    _controller: '\Drupal\flexible_google_cse\Controller\FlexibleSearchController::FgcsSearch'
    _title: 'Search'
  requirements:
    _permission: 'administer google_cse permission'

The initial patch from @heatherwoz seems to be working fine for me. It looks like the patch was created on a windows machine and has some character encoding issue but, apart from that it is working fine. It will be ported to the latest dev branch.

The first patch by @heatherwoz was missing _permission key on the routing.yml file. Thank you @Ramya Balasubramanian for the fix. This will be ported on the next release.
