feature request: add option to update the properties of a token (for example the indexes)

[BenjaminYde]

Currently the following commands are available in devpi tokens:

• token-create Create a token for user.
• token-delete Delete a token for user.
• token-derive Derive a new token from an existing token with added restrictions.
• token-inspect Inspect a given token.
• token-list List tokens for user.
• token-login Login using a token.

When creating a token, there is no option to adjust the token.
For example you cannot adjust (add / remove) the indexes of a token.

Currently you need to delete the token and create a new one, but this will create a new token value.
This is very annoying when you share tokens with clients / other people and adjustments need to happen.
It is possible to adjust an index, please add the option to adjust a token as well.

Thank you!

That's a intentional security feature
