feat(KONFLUX-4319): Capture Application & Component JSONs after load test

[rh-rahulshetty]

Description

Application and Component JSON definitions were not being captured during load test execution because the objects were cleared when the --purge flag was set.

This PR addresses the issue by moving the collection of Application and Component JSON definitions to the component handler level.

• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

The changes have been tested successfully on Hive OpenShift cluster.

# On Hive cluster - setup & install Konflux
source user.env 
./tests/load-tests/ci-scripts/setup-cluster.sh

# Run Load test
export COMPONENT_REPO=https://github.com/rh-perf-test-org/devfile-sample CONCURRENCY=1 APPLICATIONS_COUNT=2 COMPONENTS_COUNT=2
./tests/load-tests/ci-scripts/load-test.sh

At end of the load test, we should be able to find collected-application-*.json and collected-component-*.json files with the object definition for Applications and Components created during the load test.
