Review aio app logs char alias flags

**Describe the bug**

Char aliases for flags are rare and we should choose them carefully.

For example looking at:
```
poll: flags.boolean({
description: 'Fetch logs continuously',
default: false,
char: 'o',
exclusive: ['watch', 'tail']
})
```
We might want to reserve the `-o` char flag in the future to redirect output to a file via the standard `--output` flag
