Wrap fallible ORM functions in `Try`/`Catch`

[tevoinea]

Some ORM operations are fallible. We have existing code that attempts to handle the failure modes using .IsError but it turns out that they can also throw exceptions. Here's an example:

onefuzz/src/ApiService/ApiService/onefuzzlib/orm/Orm.cs

Lines 81 to 92 in 349604f

	public async Task<ResultVoid<(HttpStatusCode Status, string Reason)>> Replace(T entity) {
	var tableClient = await GetTableClient(typeof(T).Name);
	var tableEntity = _entityConverter.ToTableEntity(entity);
	var response = await tableClient.UpsertEntityAsync(tableEntity, TableUpdateMode.Replace);
	if (response.IsError) {
	return ResultVoid<(HttpStatusCode, string)>.Error(((HttpStatusCode)response.Status, response.ReasonPhrase));
	} else {
	// update ETag on success
	entity.ETag = response.Headers.ETag;
	return ResultVoid<(HttpStatusCode, string)>.Ok();
	}
	}

That example can also throw Azure.RequestFailedException.

Feature request

For all fallible ORM functions, wrap them in try/catch and return the appropriate OneFuzzResult type.
