Add onTagText to IHoverParticipant (or extend IHoverParticipant)

[AObuchow]

For the LemMinX/lsp4xml Maven extension, I would like to add support for hover request when hovering over text within a tag. Currently, IHoverParticipant only declares hovers for onTag, onAttributeName and onAttributeValue.
Since the interface is already in use, perhaps a IHoverParticipantExtension should be added, which would declare onTagText. This function would only be called when the child of a node contains only text content (and not another node/tag).

This is required for AObuchow/lsp4xml-extensions-maven#30 as well as other use cases. For a demo of the hover we are trying to implement, see this GIF.

Totally agree with you. Any pr are welcome!

No please not do that, the participant API are not frozen for the moment since we are not in 1.0.0 version

Okay sounds good!
Will the 1.0.0 version occur with the first, new release of LemMinX? (Wanted to know how much time I have to get this in before the API freeze)

Not for the moment, any PR are welcome!

@AObuchow have you an idea when you could provide a PR?

[AObuchow]

@angelozerr my next task is to work on this PR. As I haven't started yet, I'm not sure of the complexity of this task. Once I get started I'll have a better idea, and will hopefully be able to give a time estimate.

Great!

It should be very cool if we could have this feature in the next release. But if it's not possible we will do that in an another release. Don't hesitate to ask me if you need some help.

Sounds good, it was actually a lot easier than I anticipated :) I'm optimistic the feature will be ready for the next release.
