Add optional heap and CPU profiling when running Flux.

- Specify `-Pprofile[=<filename>]` to enable profiling for `:metafix-runner:run`.
- Specify `-Pprofile=true|false` to enable/disable profiling for `:metafix:integrationTest`.
- Specify `METAFIX_INTEGRATION_TEST_PROFILE=true|false` to enable/disable profiling for `metafix/integrationTest.sh`.
