This MR is an update to highlight the process by which Sales Team Members can engage legal. This includes: (i) Asking general questions related to Customers; (ii) Request editable version of GitLab Template(s); (iii) Initiating contract review / negotiation of terms.

Included in this update I have added: (i) Presentation found here https://docs.google.com/presentation/d/1lesWNvPAFd1B3RuCgKsqQlE85ZEwLuE01QpVAKPhQKw/edit#slide=id.g5d6196cc9d_2_0 (ii) Video Tutorial on how to Open a Legal Request Case, found here https://www.youtube.com/watch?v=CIWdsqRX7E0&feature=youtu.be

I've discussed this update with: @mpyle to ensure it made sense from Sales Engagement perspective. @pmachle, @james_harrison @jbrennan1 on the Sales Ops / Finance call to ensure clarity on changes. @jhurewitz and @jbraughler to ensure legals agreement on the new workflow.

Next Steps: @dhong and @james_harrison let me know if this should be added to a call, OR, if we can simply post to the Sales Slack Channel. My understanding is (correct me @jbrennan1 and @jpetr) that we may have this rolled out fairly quickly in SFDC.
