[docs/collector] Add documentation regarding data loss and resiliency

[mx-psi]

Desired feature or idea: We would like to document"

• What is the 'data loss model' for the Collector: under what circumstances does the Collector lose data and what are our recommendations to protect against them
• What type of components and deployment patterns are prone to data loss
