"""Parse the output of ``/usr/bin/lscpu``. It uses the ``CommandParser`` as the
base class. The ``parse_content`` method also converts plural keys for
better accessibility.
Ex: "CPU(s)" is converted to "CPUs"
Typical output of ``lscpu`` command is::
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 2
On-line CPU(s) list: 0,1
Thread(s) per core: 2
Core(s) per socket: 1
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 60
Model name: Intel Core Processor (Haswell, no TSX)
Stepping: 1
CPU MHz: 2793.530
BogoMIPS: 5587.06
Hypervisor vendor: KVM
Virtualization type: full
L1d cache: 32K
L1i cache: 32K
L2 cache: 4096K
NUMA node0 CPU(s): 0,1
Examples:
>>> output.info['Architecture']
'x86_64'
>>> len(output.info)
22
>>> output.info['CPUs']
'2'
>>> output.info['Threads per core']
'2'
>>> output.info['Cores per socket']
