file by instance id sdk support

[Jacob-Eliat-Eliat]

This should allow file content support to use instance id instead of just external Id.

Note: update is also supported by instance id, and will only allow updates on the fields which cannot be set using fdm. This is to be done in another PR. It is not necessary for file content support, but might be for file support.
