feat: proper backoff and port number

[leoparente]

This pull request improves the configuration handling and process monitoring of several backend components in the agent. The main changes include making port configuration more robust by accepting any value type, enhancing process readiness checks to handle unexpected process exits, and improving logging for debugging purposes.

Configuration improvements:

• Updated the Configure methods in multiple backends (deviceDiscoveryBackend, networkDiscoveryBackend, openTelemetryBackend, snmpDiscoveryBackend, workerBackend, pktvisorBackend) to accept the port configuration as any value type, converting it to a string using fmt.Sprintf. This makes the configuration more flexible and prevents type assertion errors if the port is not provided as a string. [1] [2] [3] [4] [5] [6]

Process monitoring and error handling:

• Enhanced the Start methods in several backends (deviceDiscoveryBackend, networkDiscoveryBackend, openTelemetryBackend) to check if the managed process has exited unexpectedly during readiness checks. If so, the process is stopped, an error is logged, and a descriptive error is returned. This improves reliability and error reporting. [1] [2] [3]

Logging and debugging:

• Added additional logging in the pktvisorBackend readiness check to log process status and the URL being checked, aiding in debugging startup issues.

Startup timing adjustment:

• Increased the initial sleep duration in networkDiscoveryBackend's Start method from 1 second to 4 seconds to allow more time for the process to start up before checking its status.
