Description of problem:

If you try to add an iscsi storage connection via REST API with empty target, it will fail:

POST request:
<storage_connection>
   <address>10.34.63.202</address>
   <type>iscsi</type>
   <port>3260</port>
   <target></target>
</storage_connection>

response:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<fault>
    <reason>Operation Failed</reason>
    <detail>[Target details cannot be empty.]</detail>
</fault>

However, if you create a connection with non-empty target, you can later change the target to empty:

PUT request:
<storage_connection>
   <address>10.34.63.202</address>
   <type>iscsi</type>
   <port>3260</port>
   <target></target>
</storage_connection>

response:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<storage_connection href="/api/storageconnections/28aeccb1-d72b-4742-bff2-4f9199463873" id="28aeccb1-d72b-4742-bff2-4f9199463873">
    <address>10.34.63.202</address>
    <type>iscsi</type>
    <port>3260</port>
    <target></target>
</storage_connection>


Version-Release number of selected component (if applicable): is13


How reproducible: 100%


Steps to Reproduce:
1. create an iscsi storage connection
2. try to change target to empty string

Actual results: it is possible to change an iscsi storage connection so that the target is empty


Expected results: the command should fail with the "Target details cannot be empty." error
