When converting bitrates from bits per second to kilobits per second,
if the conversion results in fractions, the resulting value should be
rounded upwards
The improved algorithm better handles some odd bitrates.
With the current version, the bitrates 63 Kbps and 65 Kbps would get
converted into 48 Kbps (unit 16 Kbps x 3) and 64 Kbps (unit 64 Kbps x
1).
Especially in the first case, the conversion error is quite signicant.
Current version tries to find the biggest 'unit', while the 'value' is
still above 0.
With the updated version, the algorithm tries to find the 'unit' low
enough, that the resulting 'value' can still fit into the 16-bit space
without overflow.
From the OpenAPI document,TS29571_CommonData.yaml : BitRate
String representing a bit rate; the prefixes follow the standard symbols from The International
System of Units, and represent x1000 multipliers, with the exception that prefix "K" is
used to represent the standard symbol "k".
ogs_pool_init() shall be used in the initialization routine.
Otherwise, memory will be fragment since this function uses system malloc()
Compared with ogs_pool_init()
ogs_pool_create() could be called while the process is running,
so this function should use ogs_malloc() instead of system malloc()

defines the AVP User-Name as mandatory. It must also be
present on failure cases.

Registration type label is not provided.
A nonstandard PLMNID label is added to achieve uniqueness.
- 5.3.1.3 Number of PDU sessions requested to be created by the SMF
PLMNID and SNSSAI are defined during PDU session creation processing.
Some requests can be rejected during processing before label values are known.
Those requests are not counted under particular labels.
To count also such requests, the basic metric with empty labels is exposed too.
```
fivegs_smffunction_sm_pdusessioncreationreq{plmnid="",snssai=""} 1
fivegs_smffunction_sm_pdusessioncreationreq{plmnid="00101",snssai="1000009"} 1
```
- 5.3.1.4 Number of PDU sessions successfully created by the SMF
```
fivegs_smffunction_sm_pdusessioncreationsucc{plmnid="00101",snssai="1000009"} 1
```
- 5.3.1.5 Number of PDU sessions failed to be created by the SMF
```
fivegs_smffunction_sm_pdusessioncreationfail{cause="400"} 1
```
Example for one successful and one failed (during creation processing) PDU session creation:
```
fivegs_smffunction_sm_pdusessioncreationreq{plmnid="",snssai=""} 2
fivegs_smffunction_sm_pdusessioncreationreq{plmnid="00101",snssai="1000009"} 1
fivegs_smffunction_sm_pdusessioncreationsucc{plmnid="00101",snssai="1000009"} 1
fivegs_smffunction_sm_pdusessioncreationfail{cause="400"} 1
```
The subscriptions to NRF should be tied to the number of NF's and number
of services per NF that we support, instead of number of UE's.
This decreases memory usage of each NF slightly, depending on the
configuration.
After N2 Handover (1 AMF, multiple gNB's) was successfully executed, the
PDU session was not properly released afterwards on PDU Session Release
Request from UE.
The reason was that after N2 Handover the new 'ran_ue' context did not
have any information about the active PDU sessions.
Copy the information about PDU sessions from old ran_ue context to the
new one.
