UTF-8 validation is missing on operational datastore

[awesomenode]

Hi,

When pushing invalid UTF-8 string into operational datastore it gets corrupted and any further get operation will fail on the whole yang module:

$ oper_data_push_example "/ietf-system:system-state/platform/os-name" $(echo -n -e '\xff') & 

Application will set "/ietf-system:system-state/platform/os-name" to value "�". 

========== WAITING AS OWNER OF SET DATA ========== 

$ sr_get_items_example "/ietf-system:system-state/platform/os-name" operational 
Application will get "/ietf-system:system-state/platform/os-name" from "operational" datastore. 

[ERR] JSON DS file: Invalid character 0xffffffff. 
[ERR] Callback "load" of plugin "JSON DS file" for module "ietf-system" failed.
 
$ sr_get_items_example "/ietf-system:system-state/platform/os-version" operational 
Application will get "/ietf-system:system-state/platform/os-version" from "operational" datastore. 

[ERR] JSON DS file: Invalid character 0xffffffff. 
[ERR] Callback "load" of plugin "JSON DS file" for module "ietf-system" failed.

Note that in case of running datastore sr_set_item*() functions fail when trying to set invalid string.

libyang version: 2.1.123
sysrepo version: 2.2.117

Thank you in advance!

Okay, the string values were often not checked at all and now they should be.
