[j-nsp] Junos 20 - slow RPD

[Luca Salvatore]

I've been down the path of very slow RPD with JTAC recently.  In our case
it was due to some mildly complex BGP community stuff that we do which was
exhausting memory limits.
A good fix for us was to bump up the memory allocation using these hidden
commands:

set policy-options as-path-match memory-limit 16m
set policy-options community-match memory-limit 16m

Default memory is 2097152 bytes, so very small.  You can see some
interesting numbers with some other hidden commands:

show policy community-match
show policy as-path-match

Also if you're running EVPN, check out this PR which is a whole world of
fun
