Review comment:
I think the use of `ok()` silently ignore errors when opening the file
and silently fallback to the repl. This leads to strange behavior for certain
files, such as those that that exists, but I don't have permissions to read
For a file such as this, I would expect `datafusion-cli` to generate an
error about permissions:
```
(arrow_dev) alamb@ip-10-0-0-124:~/Software/arrow-datafusion$ ls -l
/tmp/foo.sql
--w------- 1 alamb wheel 0B May 7 17:30 /tmp/foo.sql
(arrow_dev) alamb@ip-10-0-0-124:~/Software/arrow-datafusion$ cat
/tmp/foo.sql
cat: /tmp/foo.sql: Permission denied
```
However, the code on this branch generates no error and instead drops into
the interactive REPL loop
```
(arrow_dev) alamb@ip-10-0-0-124:~/Software/arrow-datafusion$
./target/debug/datafusion-cli --file=/tmp/foo.sql
>
```
