[JENKINS-75164] Fix Custom headers with special characters in their names

[PratikMane0112]

Fixed JIRA Issue 75164

Changes Done

In HttpRequest.java:

• Introduced logic to handle customHeaders as either a List of HttpRequestNameValuePair objects or a List of Maps with name and value keys.
• If the customHeaders is provided as a List of Maps, it is converted into a list of HttpRequestNameValuePair objects.
• If it’s provided as a Map, it is converted into a List of HttpRequestNameValuePair using the Map entries.
• Previous method is commented

In HttpRequestStep.java:

• Added the necessary imports to handle the new Map and List formats for customHeaders
• Implemented the @DataBoundSetter method to properly set customHeaders and handle conversion from List of Maps or - - - Map to a List of HttpRequestNameValuePair objects.
• Previous method is commented

Testing done

On local jenkins controller with mvn hpi:run command

• pipelines tested -

1] before & after build successfully on jenkins controller

pipeline {
    agent any
    stages {
        stage('Test HTTP Request with Custom Headers') {
            steps {
                script {
                    echo "Starting HTTP Request with custom headers"

                    def response = httpRequest(
                        url: 'https://httpbin.org/headers',
                        customHeaders: [[name: 'foo', value: 'bar']]
                    )
                    
                    echo "HTTP Response Content: ${response.content}"
                }
            }
        }
    }

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!

• Ensure that the pull request title represents the desired changelog entry

• Please describe what you did

• Link to relevant issues in GitHub or Jira

• Currently test case not done for new updated code, only testes it on jenkins controller.

• Let me know if any changes needs to be done, please also correct me if I went wrong somewhere
