Dnode alter

1. Start only one dnode

2. Modify the monitor and debugflag parameters of the online dnode

3. Modify parameters of an offline dnode (error expected)

path: cases/26-NodeManager/01-Dnode/test_alter_dnode.py

Dnode create

1. Create dnode2

2. Check system tables such as ins_dnodes and ins_mnodes

3. Create database tables on these two dnodes and perform basic write and query operations

Dnode drop force unsafe

1. Create 5 dnodes, establish a three-replica database on them, and write data

2. Create three mnodes

3. Stop one dnode and verify that it cannot be deleted

4. Use drop dnode force unsafe to forcibly delete this dnode
