Issue running solaris_exporter about solaris_exporter

[n27051538]

Hello,
This issue is driven by some changes is OS.
Max Solaris version on my hosts is 11.4.4, it works with Solaris_exporter v2021Mar01.
But this issue is the second, so I will install new test LDOM with 11.4.41 and try to improve code.
I hope that the fault is not in psutil library which I use, but which author has no time or HW to code for Solaris.

I investigated.
The old version of psutil fails due to changes in command output:
New variant:

# swap -l
swapfile                      dev            swaplo      blocks        free encrypted
/dev/zvol/dsk/bercutroot/swap 248,4               0     8388608     8388608       yes

Old variant:

$ swap -l
swapfile                    dev            swaplo      blocks        free
/dev/zvol/dsk/swapdump/swap 259,1              16   136314864   136314864

The latest version of psutil library 5.9.0 is adapted to this behavior, but the latest version of psutil not supports Python 2.7.
That is why I copied psutil code to local function psutil_local_swap_memory and adapted it.
Also I added support for Python3.7.

Please test new version v2022Feb05, I placed it into separate branch forPython3.

Just tested the python2.7 version - all working well

i will move on to test the python3.7 version
