SOAR-6425 Trendmicro Deepsecurity Fix Memory Leak- Request Session

[pmara-r7]

Proposed Changes

Remove the requests library 'session' as it can cause memory leaks, per
psf/requests#4601
Could use the .close() method on the session, but that removes the only valuable functionality that request sessions provide, so changed to using normal get and post requests.

PR Requirements

Developers, verify you have completed the following items by checking them off:

Testing

Unit Tests

Review our documentation on generating and writing plugin unit tests

• Unit tests written for any new or updated code

In-Product Tests

If you are an InsightConnect customer or have access to an InsightConnect instance, the following in-product tests should be done:

• Screenshot of job output with the plugin changes
• Screenshot of the changed connection, actions, or triggers input within the InsightConnect workflow builder

Style

Review the style guide

• For dependencies, pin OS package and Python package versions
• For security, set least privileged account with USER nobody in the Dockerfile when possible
• For size, use the slim SDK images when possible: komand/python-3-37-slim-plugin and komand/python-3-37-plugin
• For error handling, use of PluginException and ConnectionTestException
• For logging, use self.logger
• For docs, use changelog style
• For docs, validate markdown with make validate which calls mdl to lint help.md

Functional Checklist

• Work fully completed
• Functional
  • Any new actions/triggers include JSON test files in the tests/ directory created with icon-plugin run -c sample $action > tests/$action.json
  • Tests should all pass unless it's a negative test. Negative tests have a naming convention of tests/$action_bad.json
  • Unsuccessful tests should fail by raising an exception causing the plugin to die and an object should be returned on successful test
  • Add functioning test results to PR, sanitize any output if necessary
    • Single action/trigger icon-plugin run -T tests/example.json --debug --jq
    • All actions/triggers shortcut icon-plugin run -T all --debug --jq (use PR format at end)
  • Add functioning run results to PR, sanitize any output if necessary
    • Single action/trigger icon-plugin run -R tests/example.json --debug --jq
    • All actions/triggers shortcut icon-plugin run -R all --debug --jq (use PR format at end)

Assessment

You must validate your work to reviewers:

1. Run make validate and make sure everything passes
2. Run the assessment tool: icon-plugin run -A -R all -T all. For single action validation: icon-plugin run -A -R tests/my_action.json -T tests/my_action.json
3. Copy (icon-plugin ... | pbcopy) and paste the output in a new post on this PR
4. Add required screenshots from the In-Product Tests section
