blockdev parameter does not accept dots in pool name in json config
Description of problem:
I'm trying to provision a VM using qemu 6.2.0 and pass the remote disk parameters like libvirt. When I start the VM, I get an error saying 


```
qemu-system-x86_64: -blockdev {driver:rbd,pool:cloud.disk.hiops,image:csi-vol-8577fffd-0f48-3344-b333-02000038163a,server:[{host:1.2.3.4,port:6789},{host:1.2.3.5,port:6789},{host:1.2.3.6,port:6789}],user:compute-staging,auth-client-required:[cephx,none],key-secret:ceph-secret,node-name:pv-MD7PBV3SRD21L08115JUJ94HMG,cache:{direct:false,no-flush:false},auto-read-only:true,discard:unmap}: JSON parse error, stray '.'
```


I changed the ip address and some fields.


My question is should we avoid dots in pool name? I tried to look at the source code of json parser but in its doc, it did not mention a sequence of characters for escaping dots.
Steps to reproduce:
1. Provision a VM with the provided config
