add NR PDCP parameter definitions

Browse Source 
To be used in a later commit to retrieve NR PDCP configuration
parameters.

To use, add the following to the configuration file (outside of other
configurations). Adapt the values to your setup. The names ("len18bits",
"ms100", etc.) come from 3GPP TS 38.331.

pdcp = {
  drb = {
    sn_size = "len18bits"
    t_reordering  = "ms100"
    discard_timer = "infinity"
  }
}

Default values are applied if the configuration is absent.
The default values are the ones given above.
