chore: add tools.go

[aljo242]

1. Summary

Adds a tools pkg which allows us to require development tools like golangci-lint and gofumpt in our go.mod file. This is potentially useful for new devs working with our code who may not have the tools installed. Otherwise, they would receive a make target fail if they tried to run something like make format without the tool installed.

This addition also lets us ensure that all developers are using the same minimum version for said tools.

2.Type of change

Please delete options that are not relevant.

• New feature (non-breaking change which adds functionality)

3. Implementation details

• add tools/tools.go
• Use build tags to ensure these are not built into our binaries

4. How to test/use

• run go clean -modcache and remove tools like gofumpt
• run go mod tidy and then try to use tools again
