bitbake: toasterui: performance improvements

Improve the performance of data logging in toasterui.
We modify the data queries used to:

 * cache searching in memory
 * insert in bulk (i.e. multiple values per insert, where possible)

On development test rig (networked mysql), on no-op build,
time for data recording is reduced from 4:10 to 1:30 (minutes).

We also improve the logging, so it is easier to detect
toasterui errors.
