[PATCH] libosmo-sccp[master]: vty: hide SG commands when running as ASP

[dexter]

Review at  https://gerrit.osmocom.org/3453

vty: hide SG commands when running as ASP

The SG (signal gateway) requires an extra set of VTY commands in
order to be fully configurable. These VTY commands do not make
sense in a situation where libosmo-sccp is used to implement an
ASP (application server process).

Detect in which role libosmo-sccp is used by which of the VTY
initalization functions are called:

osmo_ss7_vty_init_asp() ==> ASP
osmo_ss7_vty_init_sg() ==> SG

Prevent writing back of SG specific configuration when in
running as ASP. Only write back the full parameter set when
running as SG.
