[Won't Do] Formatting changes to pbs_rstat -f output

Forum Discussion: http://community.pbspro.org/t/formatting-changes-to-pbs-rstat-f-output/1553

Motivation:

All PBS commands' long format output follows the norm that every new attribute line is printed with 4 leading spaces. But pbs_rstat -f output is printed without any leading spaces. So, it'd be more consistent with the rest of the PBS commands to add the leading spaces in pbs_rstat -f output

External changes:

Previously, a pbs_rstat -f output used to look like this:

[ravi@pbspro ~]$ pbs_rstat -f
Resv ID: R35.pbspro
Reserve_Name = NULL
Reserve_Owner = ravi@pbspro
reserve_type = 2
reserve_state = RESV_CONFIRMED
reserve_substate = 2
reserve_start = Tue Apr 16 00:00:00 2019
reserve_end = Tue Apr 16 01:00:00 2019
reserve_duration = 3600
queue = R35
Resource_List.ncpus = 1
Resource_List.nodect = 1
Resource_List.select = 1:ncpus=1
Resource_List.place = free
Resource_List.walltime = 01:00:00
schedselect = 1:ncpus=1
resv_nodes = (pbspro:ncpus=1)
Authorized_Users = ravi@pbspro
server = pbspro
ctime = Mon Apr 15 16:52:41 2019
mtime = Mon Apr 15 16:52:41 2019
Variable_List = PBS_O_LOGNAME=ravi,PBS_O_HOST=pbspro
euser = ravi
egroup = wheel

After these changes, it will look like this instead:

[ravi@pbspro ~]$ pbs_rstat -f
Resv ID: R35.pbspro
    Reserve_Name = NULL
    Reserve_Owner = ravi@pbspro
    reserve_type = 2
    reserve_state = RESV_CONFIRMED
    reserve_substate = 2
    reserve_start = Tue Apr 16 00:00:00 2019
    reserve_end = Tue Apr 16 01:00:00 2019
    reserve_duration = 3600
    queue = R35
    Resource_List.ncpus = 1
    Resource_List.nodect = 1
    Resource_List.place = free
    Resource_List.select = 1:ncpus=1
    Resource_List.walltime = 01:00:00
    schedselect = 1:ncpus=1
    resv_nodes = (pbspro:ncpus=1)
    Authorized_Users = ravi@pbspro
    server = pbspro
    ctime = Mon Apr 15 16:52:41 2019
    mtime = Mon Apr 15 16:52:41 2019
    Variable_List = PBS_O_LOGNAME=ravi,PBS_O_HOST=pbspro
    euser = ravi
    egroup = wheel
