release.

Original SR had defaults as

mme.gtp: 127.0.1.100
enb.gtp: 127.0.1.1

With this both can listen at the same port and talk to each other.

But if we set gtp addr to be the same for mme and enb, then enb listen
will fail as the listening address is already taken by mme.

Fix it with restoring explicit enb gtp loopback default.

rx_delay is meaningful to have as the default, as that is RU-model
specific and goes as T2a+T3a-Toffset.

tx_delay is less meaningful to have as the default: it is T12 + T2a,
where T2a is RU-model specific and T12 depends on the length of the
fiber link. But I keep the previous default because it might be handy to
have something as the default.

Also restore previous values for sunwave n_antenna_* as it was there in
old ors-amarisoft SR.

The code already behaved in the "updated" way with

    slaplte.jinja2:{%-     do cell.setdefault('root_sequence_index', 1 + 203*(cell.cell_type == 'lte') + n)  %}

See merge request nexedi/slapos!1531

See merge request nexedi/slapos!1529

These are already defined in stack/slapos.cfg

jupyter-py2 used an old version not py3 compatible
pygolang/test used the same version as in stack/slapos.cfg

Don't repeat slapparameter_dict['ncell_list'][k] - we can introduce a name for
current neighbour cell, and use that name in the loop. And align entries to
that they read more clearly.

No non-whitespace changes in rendered enb.cfg and gnb.cfg .

We currently have LTE-specific handover configuration in under cell_list and
NR-specific handover configuration in under nr_cell_list. Those configuration
are different.

However in upcoming MultiRU we will need to handle LTE->NR handover, NR->LTE
handover, and also Intra-ENB handover in addition to Inter-ENB handover we
currently do.

-> Move handover code into common function as a preparatory step for that.

In the future the handover code for LTE and NR cells will be the same, so it
makes sense to move that code to common place to avoid duplication.

For rendered enb.cfg this unification introduces only space and trivial
changes as shown in the appendix.
