binarystore: Enable maxBinarySize Feature

Fail on write() and commit() if the result will exceed the max size.

Enabled by adding the max_binary_size to the proto buffer. The new one
takes priority and will replace existing one even if it already exists.

The `max_binary_size` is the size of the total data including the size
header. It is calculated with
```
blob_.SerializeAsString().size() +
  sizeof(boost::endian::little_uint64_t)
```
