vtselect/vtinsert: automatic SRV record discovery and refresh for storageNode addresses #53
Description
Is your feature request related to a problem? Please describe
VictoriaTraces currently supports basic SRV record resolution for storageNode addresses using the srv+ prefix format, but lacks the automatic discovery and refresh capabilities available in VictoriaMetrics Enterprise.
Describe the solution you'd like
Supports advanced SRV discovery features including the -storageNode.discoveryInterval flag for automatic refresh, -storageNode.filter for filtering discovered addresses, and background monitoring of DNS changes.
