Describe the feature

During the writing and deployment of the service which uploads files (up to 2GB), I've encountered an issue that files bigger than 4 megabytes are not uploading. I've gone on an investigation where exactly the issue lies and eventually find out that dapr using for HTTP server fasthttp library, which by default got a 4 MB limit on max body size and in dapr code it seems that default fasthttp server is defined.
So, my question is - is it possible to add the possibility of providing MaxRequestBodySize parameter of fasthttp via annotation for example. I think I can lead that effort and provide a pull request if you guys would be okay with that kind of feature.

Release Note

Add the possibility of providing MaxRequestBodySize parameter of fasthttp server via annotation to handle uploading of big files.
