[Feature request] Allow configuration of bot limitPatches

[sebastien-hertz]

In dana-bot/src/bot.js, the globalBot.limitPatches is the maximum number of CLs to put in the queue when browsing the git log from ToT (HEAD) to the task's base. It is set to 10.

It means that if there are 100 commits between the ToT and the task's base, only the 10 most recent commits will be pushed into the queue (ToT->ToT~9). The 90 other commits (starting from the base) won't be executed.

It would be better to configure this value in dana-bot/configs/bot.js. This way, each bot can set it limit.
