Reuse go-common code and small refactoring

[martindekov]

Reusing go-common code redefined in the repo including:

• constants
• methods
• leftover feedback from previous review

Problem:
harvester/harvester#9369

Repo re-defined methods and constants which were already defined in go-common.

Solution:
Reused the methods and constants from go-common as opposed to maintaining the duality.

Related Issue:
harvester/harvester#9369

Test plan:
N/A refactoring - all tests should pass

Pull request overview

This PR refactors the codebase to eliminate code duplication by reusing constants and methods from the go-common library instead of maintaining local copies. The refactoring removes the locally defined GetHostNamespacePath() function and namespace constants, replacing them with imports from github.com/harvester/go-common/common.

• Removes duplicate GetHostNamespacePath() implementation from pkg/utils/process.go
• Replaces local namespace constants (HarvesterNS, LonghornSystemNamespaceName) with constants from go-common
• Updates prometheus/procfs dependency from v0.16.1 to v0.17.0
