Added walkthrough for users attempting to connect to MailHog server.
Connecting to the simulated mail server allows contributors to interact with features in Fleet UI that require email configuration.
Added link to development-infrastructure docs at the end of building-the-code docs to walk contributors to the next step of serving Fleet locally.
Added --auth_jwt_key="insecure" flag to fleet serve command in development-infrastructure docs.
* Perform migration to delete any entries with `deleted` set, and
subsequently drop columns `deleted` and `deleted_at`.
* Remove `deleted` and `deleted_at` references.
Closes#2146
Individuals unaccustomed to building Go projects from source may encounter difficulties cloning into the repo if they choose an arbitrary directory not in ~/go/src. Attempting to build the repo elsewhere will result in the `make deps` command failing. This change adds workspace prep instructions.
I think these were useful when none of us knew how to use glide except
@groob and needed copy-pasteable commands to run, but this seems like
it's much less useful now.
* add graceful server shutdown
Also refactors server to use `http.Server` instead of the global
http.ListenAndServe method. In the future it allows us to set
ratelimits and timeouts for http connections.
