[provider]: increase `ManifestServiceExposeHTTPOptions.MaxBodySize` from `uint32`

[ishandhanani]

Describe the bug

• account address = akash1qymxrv5sk6xc4tv9ld9avf4gkq7wpuu5rtcajx
• The relevant part of the deploy.yaml is

  expose:
    - port: 8888
      as: 80
      to:    
        - global: true
      http_options:
        max_body_size: 4294967294 #old value was 5368709120. new value is MAX_uint32 - 1 for safety

We are trying to increase the upload size to a Jupyter Notebook instance to around 5GB. However, due to the uint32 limit, we cannot increase past ~4GB.

To Reproduce Steps to reproduce the behavior: Create an SDL with the http_options shown above. The cloudmos proxy throws

Status code was not success (422) : json: cannot unmarshal number 5368709120 into Go struct field ServiceExposeHTTPOptions.services.expose.httpOptions.maxBodySize of type uint32

Expected behavior This is expected as the limit is uint32

Potential fix Increase that field to uint64. The relevant code is here. Thank you!
