Yang error messages - RFC7950

yang defined error-messages are supported for the following yang statements.

• 7.5.4. The must's Substatements

• 9.2.4.1. The range's Substatements

• 9.4.4.1. The length's Substatements

• 9.4.5.1. The pattern's Substatements

Example:

^{[...]
must "./ssh-connections + ./tls-connections <= 100" {}

^{error-message "The total number of connections (SSH + TLS) needs to be less than or equal with 100.";
}
[...]}

Result in odl-restconf-nb-baermann

^{{
"errors": {
"error": [
{
"error-type": "application",
"error-tag": "operation-failed",
"error-message": "Commit of transaction org.opendaylight.netconf.sal.connect.netconf.sal.tx.WriteCandidateRunningTx@2aa1fb85 failed",
"error-info": "RemoteDevice{NTS-manager}:RPC during tx failed. The total number of connections (SSH + TLS)
needs to be less than or equal with 100."
}
