Include SHA1 hash when deleting a file

[christianwaldmann]

What does this PR do?

• This adds the CLI option --display-format to customize the printed message when deleting a file
• This PR adds the SHA1 hash to the output when deleting a file
• Fixes a slight inconsistency between the formatting when deleting a file in dry mode vs. destroy mode

Motivation

• This information (SHA1 hash) can be helpful for recovering accidentally deleted files later on, as Artifactory uses Checksum-based Storage.

More

• Added tests

Let's add it by default if there's sha1 from artifactory!

That would be useful for "export data" as well

[christianwaldmann]

Changed the default to include the sha1 hash.

I'm not sure what you mean by "export data", because the option --output is only printing the summary and not the deleted files. Therefore a hash doesn't make sense there.

Changed the default to include the sha1 hash.

Oh, sorry, I meant only that, without any additional changes.

I don't see the point of having flex format if we manually replace it later.

--output is only printing the summary and not the deleted files. Therefore a hash doesn't make sense there.

I thought it was merged already, but it's not. Never mind!
#136

[christianwaldmann]

Got it, a fixed format including the hash works fine for me too.

I updated the PR and description accordingly.
