create improving metrics directory and remove no ext. files from partners/solutions root

This PR addresses files that were created in the root of website/partners/solutions.  These files had no file extension and were not created in the proper convention of company name = directory name, file within this directory `index.hbs`.

I removed `AGconsult` because it was already fixed and merged in a previous PR.  I also create a `improving-metrics` directory, and moved the `improvingmetrics` file into this directory renaming it `index.hbs`
