bitbake: toaster: Analysis API variablehistory update
This patch updates the Analysis REST API to expose
the variablehistory information. A UI tool can query
this API to get a picture on how a variable value got
to its final form.
The documentation for VariableHistory is updated on
Wiki https://wiki.yoctoproject.org/wiki/Analysis_REST_API_Contracts
