### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
IN CLOUD
1. add some cloud metaservice api regression test
2. prohibit one node add to multi cluster repeatedly
3. supports switching from master observer mode to multi follower mode, and
compatible with upgrading from existing master servers deployment mode to multi
providers mode
4. when adding an FE node(add fe cluster, add fe node), there is a 5-minute
protection time and the FE node cannot be droped(drop fe cluster, drop fe node)
5. drop the node. If the node cannot be found, an error will occur and the
code will return 404 instead of the previous silent processing
6. If the MS node starts with 127.0.0.1 IP and the
`prohibit_use_loopback_addresses` is set to true(default), the MS node will not
be able to start, ms log will find `enable check prohibit use loopback addr,
but localhost=127.0.0.1, so exit(-1)`
