state: write the version number in plain text on top of state files
We will soon be using CBOR format to write the data in state files. But we
should not write the version number of the state files in CBOR format and we
should rather write it in plain text because in future we can change the format
of state files and we should be able to parse the version number of state file
without requiring to understand a certain format.
This will help us in making sure we have a good compatibility story with other
versions of state files.
