This function uses the completion item object to retrieve tooltip information
by parsing R help documentation and rendering to html.

shinyServer
An observer reference class object that is responsible for offering
completion tooltips. See observe for more details. You
can use suspend or destroy to pause to stop dynamic code
completion.
The observer reference object will send a custom shiny message using
session$sendCustomMessage to the docTooltip endpoint containing a
json list of completion item metadata objects. The json list should have a
structure akin to one of:
A text object
<str: text to display for tooltip>
An object containing a docHTML property
{
docHTML: <str: html to display for tooltip div, used if available>,
}
An object containing a docText property
{
docText: <str: text to display for tooltip div>
}
You can implement your own tooltips by observing modification events to
input$<editorId>_shinyAce_tooltipItem where <editorId> is the
aceEditor id. This input contains the object passed to codeCompletion
for this item. See the help for aceAutocomplete for details on
the fields of the completion item object.
