exec_mode default value is cluster instead of fork

[AoDev]

What's going wrong?

The docs say that the default exec_mode is fork. However, when exec_mode is not defined in the config, my processes start in cluster mode.

How could we reproduce this issue?

A config without exec_mode defined.

I am using PM2 v4.2.3
