This commit introduces a comprehensive global synchronization feature that enables synchronization of global objects between Doris clusters. Features: - Support for global snapshot creation with configurable options - Flexible sync options: all, backup_privilege, backup_catalog, backup_workload_group - Automatic backup completion monitoring with timeout handling - Global snapshot information retrieval and processing - SQL statement execution on destination cluster - Comprehensive error handling and logging throughout the process API Endpoint: - POST /sync_global - Handles global synchronization requests Request Structure: - name: Unique identifier for the sync operation - src: Source cluster specification - dest: Destination cluster specification - Sync options (at least one required if 'all' is not set): - all: Sync all global objects - backup_privilege: Sync user privileges - backup_catalog: Sync catalog information - backup_workload_group: Sync workload group settings Workflow: 1. Create global snapshot on source cluster 2. Wait for backup completion with polling mechanism 3. Retrieve global snapshot details via RPC 4. Convert snapshot data to SQL statements 5. Execute SQL statements on destination cluster Additional improvements: - Internationalize all Chinese logs and comments to English - Refactor validation logic for flexible option combinations - Decompose syncGlobal function into smaller, focused functions This feature enables seamless migration and synchronization of global configurations between Doris clusters, supporting various deployment scenarios including disaster recovery and cluster migration.

Add cluster-level CCR job creation.
By setting cluster_sync: true in the JSON body, a single POST to /create_ccr will automatically synchronize every database and table from the source cluster to the destination cluster
Usage example
curl -X POST -H "Content-Type: application/json" -d '{
"name": "ccr_full",
"cluster_sync": true,
"src": {
"host": "10.0.2.132",
"port": "9030",
"thrift_port": "9020",
"user": "root",
"password": "XX",
"database": "",
"table": ""
},
"dest": {
"host": "10.0.4.252",
"port": "9030",
"thrift_port": "9020",
"user": "root",
"password": "XX",
"database": "",
"table": ""
}
