feat: proxy support muit avs

[fyInALT]

Now proxy will bind hander by avsName, for example, if the proxy address is 10.1.1.10, the avs cfgs are:

[
  {
     "avs_name": "altLayer_mach_avs",
     ...
  },
  {
    "avs_name": "xterio_mach_avs",
     ...
  }
]

Then the verifier can call:

• http://127.0.0.1:8092/xterio_mach_avs
• http://127.0.0.1:8092/altLayer_mach_avs

for each avs.

So we can just boot one proxy for muit avs.
