Cloudbeat panics on configuration changes

[orouz]

Describe the bug

cloudbeat panics after getting a new config (for example, updated integration version). it ends up restarting, but it shouldn't panic

To Reproduce
Steps to reproduce the behavior:

1. Install integration and deploy an agent
2. Send reconfiguration by doing one of the following:
   • edit integration values other than name, if possible
   • update integration version
   • change agent log level
3. monitor agent logs and look for:
   1. configuration change
   2. fatal panic error

Expected behavior

cloudbeat handles reconfiguration gracefully and restarts without panic
