Every service method built and disposed its own PveHttpClient, and each
client owned a fresh HttpClientHandler, so every API call was a TCP connect
plus a TLS handshake and WaitForTask paid that 300 times over a ten-minute
wait.
PveServiceBase now owns the injected-or-fresh client lifetime behind one
Invoke helper; the 201 hand-written try/finally blocks across the 16
services collapse to calls on it, and the nested NodeService/VmService
instances receive the injected client. PveHttpClient takes its handler
from a process-wide PveHandlerCache keyed on (host, port,
skipCertificateCheck) and never disposes it, so the connection pool
outlives any one client. WaitForTask holds one client for the whole wait
and, when no pollInterval is supplied, backs off from 1 s toward a 10 s
cap, never sleeping past the deadline.
