dhcp-server: T4344: Fix underscores for shared network name

Shared network name should not be handled by tag node mangling
I.e. should not replace underscores with dashed

set service dhcp-server shared-network-name NET_01

shared-network NET_01 {
    authoritative;
    ...
    on commit {
        set shared-networkname = "NET_01";
    }
}

(cherry picked from commit b75b351b7dd2ec87407f98668468b1fc146428bf)
