The problem is that on one MX304 end customer is not able to get any telemetry data for /junos/services/label-switched-path/usage path.

For UHP egress LSPs & P2MP LSP stats, rsvp creates sensors with empty lsp-names.

When these sensors with empty lsp names get installed into PFE, it leads to wrong data being exported to collector since name is part of the key.

This is fixed via internal PR 1888311.

As a fix, encode lsp name when sensors are being created.

We can find same in pfe as blank values without lsp name.
