NSFS endpoint should set its process/threads name in the OS to be identified accurately

Is your feature request related to a problem? Please describe.
We want GPFS to identify the noobaa endpoint processes so that it can assist with #8039.

Describe the solution you'd like
Use one of https://linux.die.net/man/2/prctl or pthread_setname_np or setprocname or setproctitle (need to figure out which one) in order to set the process name to "noobaa".

Describe alternatives you've considered
We considered adding a special libgpfs library call that will set the calling process attributes, but setting the name is less coupled.

@eshelmarc Should I set the process title (setproctitle) ? this is the property you will get?
