Closes #138 IOS-XE certificate validation

[netgab]

Added the option to control certificate validation, to the device connection as:

devices:
  eWLC:
        os: iosxe
        type: eWLC
        custom:
          abstraction:
            order: [os]
        connections:
          rest:
            class: rest.connector.Rest
            ip: 198.51.100.3
            #verify: True                  # <-- Enable certificate validation (default)
            verify: False                  # <-- Disable certificate validation

This setting is applied to the requests.session object once, which is applied to all following operations like GET, POST etc.

I guess the pipeline fails, because Python 3.8 is EoL
https://devguide.python.org/versions/

The runners don't support Python 3.8

Error: Version 3.8 with arch x64 not found
Available versions:

3.10.16 (x64)
3.11.11 (x64)
3.12.8 (x64)
3.13.1 (x64)
3.9.21 (x64)

Should the file CiscoTestAutomation-rest/.github/workflows/run_tests.yml also be modified, to exclude python-version 3.8?

shouldn't this default to False?

Suggested change

	self.verify = self.connection_info.get('verify', True)
	self.verify = self.connection_info.get('verify', False)

[netgab]

As of today, it defaults to True for the get requests (as no verify parameter is passed there).
Furthermore, I guess a good security practice is, to enable SSL/TLS certificate validation by default and only disable it, if there are specific reasons.

[oboehmer]

I don't argue, even if test tools often interact with lab devices where certificate discipline is often, err, sloppy..
but in the PR description you mentioned

            verify: False                  # <-- Disable certificate validation (default)

Sorry @oboehmer .. my bad. I updated the PR description above
