Change the open file limits and kernel parameters

Change the kernel parameters that need changing.

```
# Change the open file limits in /etc/security/limits.conf
RUN sed -i '/.*End of file/d' /etc/security/limits.conf
RUN echo "* soft nofile 16384" >> /etc/security/limits.conf
RUN echo "* hard nofile 16384" >> /etc/security/limits.conf
RUN echo "# End of file"  >> /etc/security/limits.conf

#Change the kernel parameters that need changing. 
RUN echo "net.core.rmem_max=4192608" > /u01/oracle/sysctl.conf
RUN echo "net.core.wmem_max=4192608" >> /u01/oracle/sysctl.conf
RUN sysctl -e -p /u01/oracle/sysctl.conf
```
