the right limits are applied

What is changed, added or deleted? (Required)

If the [email protected] (where 1001 is the uid of the tidb user) is started before /etc/security/limits.conf is adjusted this causes the services to not get the right NOFILE limit applied and leads to various issues.

There are three options for this:

• Restart the service after limits.conf has been modified
• Restart the machine after limits.conf has been modified.
• Modify limits.conf before the service is started.
