Add use cases/issues with solutions

[ritwik12]

In addition to the material with basic concepts, we should give a practical example of some issues that an SRE deals with in his/her day to day life.

Few common cases:

• Dealing with information in Logs: Scrapping logs, finding errors and warnings.

• Troubleshooting an issue with Web App: Using the inspect to find any network, console errors.

• Working with Servers: Check Health, status of an APP, CPU usage, Memory Utilization. etc.

These are just common thought use cases, We can deep dive and find more appropriate practical cases to put on the site.

These are really good points
Based on the feedback we sense that we missed out monitoring, troubleshooting and deployment patterns which are some of the key skills in SRE role
We are happy to receive PR with the content being generic and shedding more light on fundamentals and philosophy than being specific to any tools.

We will as well try to see if our core group can spend some time here. We will update the thread with timelines if we commit to it shortly
