Setting additional (data-)attributes on the rendered script/link tag

[henrykuijpers]

It would be nice to be able to set additional attributes on the rendered script/link tags.

In our case, we want to specify "rel" and "title", and also "data-contrast" to indicate that our stylesheet is for the contrast option.

It would be good to change the HTL helper, for example by allowing the specification of a map (or similar), so that any attributes can be specified and we don't have to deal with a hardcoded list of supported attributes. This way, we don't have to do code changes when something new needs to be supported.

i've a proposal in #2 - can you give it a try?

<sly data-sly-use.clientlib="/apps/wcm-io/wcm/ui/clientlibs/sightly/templates/clientlib.html"
    data-sly-call="${clientlib.css @ categories=['my-clientlib-category'],
    customAttributes=['attr1=value 1','data-attr2=5','attr3']}"/>

<sly data-sly-use.clientlib="/apps/wcm-io/wcm/ui/clientlibs/sightly/templates/clientlib.html"
    data-sly-call="${clientlib.js @ categories=['my-clientlib-category'],
    customAttributes=['attr1=value 1','data-attr2=5','attr3']}"/>
