Allow clients to explicitly set the sequnece for LumiBlockMuWriter algorithm
Added sequence argument to the LumiBlockMuWriterDefault() function. If the argument
is set, then this sequence is used for LumiBlockMuWriter. Otherwise the appropriate
sequence is chosen by the LumiBlockMuWriterDefault() function itself.
In TriggerJobOpts: Moved the xAODEventInfoCnvAlg and LumiBlockMuWriter algs from AthCondSeq
to HLTBeginSeq and moved the corresponding configuration to a place just after
HLTBeginSeq is created.
