Introduce facts-tracker (#7747)
* Introduce facts-tracker We want to be able to track various things like number of files that are flowified, number of tests passing with Fiber... This introduces a tool that lets you do that. The API is very simple, you execute the script with a list of tuples [key value] and it's going to create a `facts` branch and put a txt file for each fact and values over time. ``` node scripts/facts-tracker/index.js \ "flow-files" "$COUNT_WITH_FLOW/$COUNT_ALL_FILES" ``` Test Plan: This is tricky to test because Travis only exposes the private variables (github token) when it processes a committed file and not on branches. The reason is that otherwise anyone could send a pull requests that does `echo $GITHUB_TOKEN` and steal your token. Given this constraint, I did all the work using two of my repos: - https://github.com/vjeux/facts-tracker - https://github.com/vjeux/facts-tracker-test and am sending this pull request that should work as is /fingers crossed/, but we won't be able to test it out until it is committed. Note that once this lands, I'm going to kill those two repos. * Update with all the suggested changes * Branch on a flow type in travis.yml * Use $GITHUB_TOKEN * properly escape it
