fix(integration-tests): Support Non Debian/Ubuntu based Machines for executing improved_e2e integration tests

[PranjalC100]

Description

Issue: Integration Scripts Incompatible with RHEL Environments

1. Error in improved_run_e2e_tests.sh
The script failed because it relies on apt-get, which is specific to Debian/Ubuntu systems.

2. Error in ./perfmetrics/scripts/install_go.sh
The Go installer failed because it used dpkg to determine the system architecture, causing the installation to be skipped on non-Debian distributions.

Solution

To support multiple Linux distributions (RHEL, Debian, etc.), the scripts were updated to be distro-agnostic:

• Architecture Detection: Switched to system_arch=$(uname -m) to detect the architecture without relying on package managers.
• OS Detection: Implemented a check using /etc/os-release to dynamically select the correct package manager (apt-get, yum, etc.):

  if [ -f /etc/os-release ]; then
      . /etc/os-release
      # Execute install commands based on $ID

Created a new centralized script perfmetrics/scripts/os_utils.sh to handle OS and architecture detection as well as package installation logic.

Testing details

1. Manual - Ran the new Manual CD script in gcsfuse-tools to test on a rhel based machine. The run was successful, logs at http://shortn/_iakOVsppDv

Any backward incompatible change? If so, please explain.

Looks good! have added e2e labels for running tests on kokoro.
