V2 Configuration Reloading Checklist

[michalpristas]

Before merging V2 branch we need to make sure other functionality introduced/used in previous model works as expected today:

• reloading proxy settings, all clients are using desired proxy config
• reloading download config, upgrade downloads agent from desired path
• reloading monitoring config, when config changes monitoring is shut down/altered
• reloading log level, beats and agent are unable to reload log level on the fly make sure it still works
• reloading artifact config is still functional (sourceURI, timeouts, drop path)
• make sure included config files make sense and agent consumes/parses them correctly

These should be verified, in case feature does not work let's create separate issue and link it to this one.
