Starts the application by configuring all endpoints servers to run.
## Command line options
This task accepts the same command-line arguments as `run`.
For additional information, refer to the documentation for
`Mix.Tasks.Run`.
For example, to run `phoenix.server` without checking dependencies:
mix phoenix.server --no-deps-check
The `--no-halt` flag is automatically added.
