[GSoC][PATCH v7 1/6] advice: add sequencerInUse config variable

[Rohit Ashiwal <rohit.ashiwal265@gmail.com>]

Calls to advise() which are not guarded by advice.* config variables
are "bad" as they do not let the user say, "I've learned this part
of Git enough, please don't tell me what to do verbosely.". Add a
configuration variable "sequencerInUse" which controls whether to
display advice when any sequencer command is in progress.
