vty: do not change number_endpoints at runtime
The variable number_endpoints is used as a length indicator
for the array that contains the trunk endpoints at all times.
When osmo-mgw is startet up, the variable is set and osmo-mgw
will allocate the memory for the endpoints. However, it is
still possible to manipulate the variable via the telnet
interface. When the value is increased osmo-mgw might start
using unallocated memory at some point.
Store subsequent changes of number_enspoints in a separate
variable in order to write them to the config file. The
changes will then take effect after a restart.
Closes: OS#2632
