Jenkins pipeline添加自动获取分支案例

在jenkins构建时，自动从git获取所有的分支名，并显示出来供用户选择过滤

效果图：

pipeline代码示例

pipeline {
    agent any

    options {
      buildDiscarder logRotator(artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '15', numToKeepStr: '15')
    }
     parameters {
            string defaultValue: 'https://gitlab.haojiequ.com/dtkgo/dtk_go_app_api.git', description: '项目的git地址', name: 'GIT_PROJECT_URL', trim: false
            choice choices: ['test1', 'test2', 'test3', 'huise', 'dev1'], description: '选择发布环境，默认发布至test1测试环境', name: 'PENV'    
            gitParameter name: 'GIT_BRANCH', 
                         type: 'PT_BRANCH_TAG',
                         branchFilter: 'origin/(.*)',
                         defaultValue: 'master',

                         description: 'Select your branch or tag.'

        }

    stages {
