This change aims to keep versions of mockery consistent across developer laptops.
This change adds mockery to the `tools.go` file so that its version can be managed consistently in the `go.mod` file.
Additionally, this change temporarily disables adding mockery's version number to generated files. There is an outstanding issue against the mockery project related to the version string behavior when running from `go get`. I have created a pull request to fix this issue in the mockery project.
see: https://github.com/vektra/mockery/issues/397
There are many `//go:generate mockery` lines in the source code.
This change adds a make target to invoke these mock generations.
This change also invokes the mock invocations and adds the resulting mocks to the repo.
