Revert "poetry 1.2.0"

[ghyde]

This pull request reverts poetry from 1.2.0 to 1.1.15. 1.2.0 currently breaks bash completion for poetry, resulting in the error:

/usr/local/etc/bash_completion.d/poetry: line 40: syntax error near unexpected token `clear'
/usr/local/etc/bash_completion.d/poetry: line 40: `            (cache clear)'

This can be reproduced by running the command bash /usr/local/etc/bash_completion.d/poetry.

I don't think we want to revert this. CI also won't pass anyway.

This should be reported upstream and fixed there. We can backport any necessary patches when that's done.

Upstream poetry issue python-poetry/poetry#4572 was determined to be a cleo issue and fixed in python-poetry/cleo#247

Can try backporting patch for cleo resource.

Hi, Cleo and Poetry maintainer here. We are closing in on releasing Cleo 1.0 stable version and it will be backported to Poetry 1.2 as soon as it is available. You can track the progress of getting Cleo to 1.0 here: python-poetry/cleo#248

Closing this PR as we are now waiting for a new release with the fixes or waiting for a patch that can be applied to the current version.
