jobsApi config/create method misses "+" in <command> tag

[ozvale]

parts of jobXml content:

<builders>
        <hudson.tasks.Shell>
            <command>set +x
                bash -c &quot;${shell}&quot;</command>
        </hudson.tasks.Shell>
</builders>

when i called client.api().jobsApi().config(null, jobName, jobXml)) or client.api().jobsApi().create(null, jobName, jobXml))
"+" in command tag will be replace to " "
jenkins job build execute shell:

set   x
bash -c "${shell}"

i try to send a similar request with postman,it is correct.

Expected Behavior

jobXml command tag content support "+" for creating or updating

Current Behavior

see jenkins job build shell below

set   x
bash -c "${shell}"

"+" is missing

Context

when i called client.api().jobsApi().config(null, jobName, jobXml)) or client.api().jobsApi().create(null, jobName, jobXml))
"+" in tag will be replace to " "

Steps to Reproduce (for bugs)

• create a job by jenkins page,set build->execute shell-> set +x
• call client.api().jobsApi().config(null, jobName)) get jobXml,"+" exists in command tag
• call client.api().jobsApi().config(null, jobName, jobXml),see jenkins server config page ,"+" is missing

@ozvale @zk279444107 I'd be open for someone sending in a PR to fix this as at the moment I simply do not have the time.
