git fetch should build a history when possible

[shadiakiki1986]

Based on feedback here from u/ZiggyTheHamster, some remotes such as aws+ec2://describe-instances could support pulling a full history of changes using AWS CloudTrail.

More feedback from u/XNormal:

• summary comment 1: need history + AWS config lambda to capture history
• summary comment 2: log changes into real git repo
• summary comment 3: can store git history in cloudtrail as custom event
• summary comment 4: two git logs, format for good diff --color-words, tool that takes 2 commits and generates aws cli commands to go from 1 commit to the other
