tracking of used resources

[despiegk]

we need a feature where we track used resources in line to

• mem
• cpu usage
• network usage for specified interfaces only (accounting of network usage)

it should be logged per e.g. 5 min (avg during that min)
can be logged in a file e.g. 1 file per day per process

there should be a flag which specifies if we want to track resources or not

this features is needed for tracking in zos 4

using zinit will give us a generic way how to do this
