User Cron and Cron log support from jailshell on ubuntu

Hello,

I believe that RHEL variants can run cronjobs inside of a jailshell, while on Ubuntu that does not seem to be the case. I'd think it'd be more ideal and safer to run client processes inside of a jailed shell environment rather than outside of it. This should also produce user cron logs inside of the users own /home/$user/logs folder. The jailshell would simply need access to whatever php version the cpanel account is using which i believe is already the case, and the following files from what I see would have to be included inside of the jailshell:

ldd /usr/bin/crontab
