Implement a new dbus method to set advertising intervals.
The advertising inervals are sent through a new mgmt method with
the opcode MGMT_OP_SET_ADVERTISING_INTERVALS to bluetooth kernel
subsystem.

I feel this should be per instance settings, and if we want this level of
finetuning we would probably need to have new command for adding advertising
sets (where we could fix more, eg not limit data to 255 bytes).
Other option would be to maybe have new flags in current Add Advertising that
would allow to choose from low,med,hi (eg based on GAP recommended values)
intervals, and then allow to finetune those via extra command or sysfs?
Just my two cents.

+1, since we need to accomodate for the case of having multiple
application having their own instances having some presets might be
easier to manage.

Perform the following steps to verify advertising intervals.
Open a terminal on the DUT, and execute
$ btmon
Open another terminal on the DUT, and register an advertisement.
$ ./example-advertisement
Observe that the default intervals are 1280 msec in btmon log.
< HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15
Min advertising interval: 1280.000 msec (0x0800)
Max advertising interval: 1280.000 msec (0x0800)
Press ctrl-c to terminate the advertisement.
Set new intervals to 200 ms.
$ ./example-advertising-intervals 200 200
It would show the following line in btmon log.
= bluetoothd: Set Advertising Intervals: 0x0140, 0x0140
Register an advertisement again.
$ ./example-advertisement
Observe that the new intervals bcome 200 msec in btmon log.
< HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15
Min advertising interval: 200.000 msec (0x0140)
Max advertising interval: 200.000 msec (0x0140)
Press ctrl-c to terminate the advertisement.
