optic index info outputs empty report header

[slippman]

When using the --clusters argument with the optic index info command - if there is not at least one valid cluster provided, optic outputs an empty report header.

7536 ➜ optic index info -c typo-clustername
typo-clustername is not present in cluster configuration information

Suggested remedy: optic should not output the report header but instead an informational message stating that there are no valid indexes to report on.
