user-manual-metadata.xml: Rewrite "Accessing Datastore Variables Using Python"

Rewrote this section.  Used a table instead of the funky list
that was there.  I still need to format it some.

Also fixed up the term "datastore".  It should not be "data store"

-            It is often necessary to manipulate variables within python functions
-            and the Bitbake data store has an API which allows this.
-            The operations available are:
-            <literallayout class='monospaced'>
-     d.getVar("X", expand=False)
-            </literallayout>
-            returns the value of variable "X", expanding the value
-            if specified.
-            <literallayout class='monospaced'>
-     d.setVar("X", value)
-            </literallayout>

-     d.appendVar("X", value)

-            <literallayout class='monospaced'>

-            <literallayout class='monospaced'>
-     d.delVar("X")
-            </literallayout>

-            <literallayout class='monospaced'>
-     d.renameVar("X", "Y")

-            <literallayout class='monospaced'>
