Allow meta-service groups to carry a default enabled state in config. Preserve the legacy address-only form, keep runtime status authoritative when it already exists, and cover the new behavior in config, keyspace, and handler tests. Signed-off-by: ystaticy <y_static_y@sina.com>

Suggested reviewers: Merge Risk: 🟡 Moderate · up to Adding a meta-service group now probes each supplied etcd endpoint before persistence, but an authorized configuration request can still make PD initiate health checks to unrestricted destinations.

applicable TLS configuration into the clientv3.Config used for the etcd health
check, setting Config.TLS consistently with the manager’s etcd connection
settings so TLS-secured endpoints remain healthy.

request-provided group addresses are restricted before being assigned to

destination validation or authorization mechanism, and reject private/internal

CWE: CWE-918 — Server-Side Request Forgery (SSRF)
Restrict destinations before the health check.
When the PATCH adds a new group, UpdateGroupsSafely passes each request-provided address to clientv3.Config.Endpoints and performs an etcd health check. No destination restriction appears in this path. Reject private and internal targets before the health check, or enforce equivalent authorization for this endpoint.

64-64: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winCopy maps before the manager stores them.
These assignments retain caller-owned maps. A caller can mutate the map after construction or update while manager methods read it under the manager lock. The external mutation bypasses that lock and can cause a concurrent map read/write failure. Restore a map copy at both ownership boundaries.
As per coding guidelines, “Guard shared state with mutex/RWMutex; keep lock ordering consistent.”

What problem does this PR solve?
Runtime meta-service group additions could persist unreachable etcd endpoints.
A later status update could then enable a group that cannot serve assigned
keyspaces.
