Can't find kea-control-agent hook control-agent-commands.so with kea-2.2.0

name: Bug report
about: Can't find kea-control-agent hook control-agent-commands.so with kea-2.2.0

Describe the bug

I installed kea dhcp using source code. And the compilation parameters are as follows:

Configure arguments:
  '--prefix=/opt/kea' '--with-mysql' '--with-log4cplus' '--with-boost-include' '--with-botan-config' '--with-openssl' '--enable-shell' '--with-site-packages=/lib/python3.6/site-packages' '--enable-perfdhcp' 'runstatedir=${localstatedir}/
run'

But I can't find the control-agent-commands.so hook file in kea hook dir, I also checked the entire file system and couldn't find this file.

So what is the reason why there is no such file? I need your help to solve it, thank you!
