Allow hashDigestLength to be used by other loaders

[rightaway]

Feature request

What is the expected behavior?
Every loader that uses [hash] needs to use [hash:10] to be consistent if webpack's options were set as output: { hashDigestLength: 10 } }. It would be better if loaders were able to use the same value by default if they choose to.

What is motivation or use case for adding/changing the behavior?
hashDigestLength should be able to be used by [hash] in file-loader and other loaders if they choose to, so that [hash] would by default have a length of 10.

How should this be implemented in your opinion?
In webpack/loader-utils#121 (comment) it says that the issue should be solved on the webpack side. There was also an issue in file-loader project which said it can't be solved there.

Are you willing to work on this yourself?

@rightaway Please read my answer in the issue, we already have an issue for providing some output options for loaders, no need duplicate

Sorry I didn't see that issue you're referring to. It's not linked from webpack/loader-utils#121. Could you please link that issue here so I can follow the correct one?
