### Description
using KEMI API in Python v2.7.18 for Kamailio v5.6.2, I encounter error in `ksr_onsend_route`, it always gives following error,
```
ERROR: app_python [python_support.c:154]: python_handle_exception(): apy_exec: ksr_onsend_route((null)): Unhandled exception in the Python code:
TypeError: an integer is required
```
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
### Troubleshooting
Above error happens even if there is no code in this function and it returns success, e.g.
``` python
...
def ksr_onsend_route(self, msg):
return 1
...
```
#### Reproduction
It happens always whenever `ksr_onsend_route` function exists in `kamailio` class in KEMI python configuration for kamailio.
<!--
If the issue can be reproduced, describe how it can be done.
-->
#### Debugging Data
Nothing relevant in debug even with `debug=9` set.
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

#### Log Messages
<!--
Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).

#### SIP Traffic

If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).

### Possible Solutions
I suspect the problem is at low level (native code) of app_python module.

### Description
When I use Kamailio 5.6 with kazoo config file, then can see error messages:
```
WARNING: <core> [core/rvalue.c:1043]: rval_get_int(): automatic string to int conversion for "63823655406" failed
WARNING: <core> [core/rvalue.c:1949]: rval_expr_eval_int(): rval expression conversion to int failed (140,54-140,73)
```
This warning message related to commit bcd59d73e2fc5ae8e14cad520e726ef431f0563f.
Kazoo sending timestamp using the Gregorian format and timestamp value greater than max int value.
As a result, JSON string values with a timestamp cannot be parsed and converted to int.
As I understand required to add long format support into Kamailio.
This was tested using this Kamailio config.
```
listen=udp:127.0.0.1:5060
######## Advanced logger module ########
loadmodule "xlog.so"
######## Generic Hash Table container in shared memory ########
loadmodule "htable.so"
event_route[htable:mod-init] {
if ( 63823655406 > 0 ) {
xlog("L_ERR", "*** Kamailio support long data type!\n");
} else {
xlog("L_ERR", "*** Kamailio not support long data type!\n");
}
}
```
### Expected behavior
Kamailio is able to convert strings to long data type.
#### Actual observed behavior
Kamailio was not able to convert strings to long data type.
@lazedo, probable you want to know about this behavior.
