fix: command "pm2 reloadLogs" does not respect silent flags when used in daemon mode (like when executing with Node.js child_process.exec)

[t-poirier]

When programmatically executing "pm2 reloadLogs" like with child_process.exec, the flags -s and --silent are not respected because the command is passed through pm2-axon-rpc. The only way I found to obtain the desired behavior is to introduce a dedicated command "pm2 reloadLogsSilently" that does the job.

This is useful to avoid the pollution of the console messages when rotating the logs.
