[LU-18638] print project name with 'lfs project'

Description

Currently 'lfs project' only prints the project id followed by the file name, it could be useful to print the project name instead of the id (if available, otherwise still print the numeric projid). A new "-n" option can print the numeric value in all cases, similar to "ls -ln". Something like:

$ lfs project -p quota_usr /mnt/lfs1/tfile 
$ lfs project /mnt/lfs1/tfile 
quota_prj - /mnt/lfs1/tfile
$ lfs project -n /mnt/lfs1/tfile 
1000 - /mnt/lfs1/tfile
