Added sopport for insecure mode (skip verification certs)

[juliancnn]

Description

Part of wazuh/wazuh#27174

This PR adds the functionality to make optional the verification of certificates against a CA, also modifies the test tool to verify this behavior.

Example

Skipping validation against opensearch

╰─# ./urlrequest_testtool -u "https://localhost:9200/_cluster/health?pretty=true" -t get --skip-verify-peer true --username admin --password admin
{
  "cluster_name" : "opensearch-cluster",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "discovered_master" : true,
  "discovered_cluster_manager" : true,
  "active_primary_shards" : 5,
  "active_shards" : 5,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

Without skipping validation
