RD developments towards June TS

Depends on Rec!3902 and lhcb-datapkg/ParamFiles!87

Overall impact on bandwidth

Taken from this test, corresponding to c77212e3

Goals

Include modifications towards the deadline of May 15th, following !3157 (merged). Related to #710. These changes include tweaks to lines, bug fixes and the inclusion of downstream lines.

Modifications to be included:

• Bring rates and bandwidths down to a reasonable level < 100 Hz, < 10 MB/s
• Understand the lines that report empty monitoring plots #761
• Implement more lines that require downstream reconstruction #662
• Tackle the issue of having lines that make too many combinations #756, #737, #705 (closed)
• Remove duplicated lines #704
• Revisit the prescales of the lines based on HLT1 filtered minimum bias data
• Bug fix for Upsilon(2s) -> Upsilon(1s) pipi line @rquaglia [ see parent_id fix from in !3425 (merged) ]

Contributing

If you want to contribute to this MR, please speak first to @mramospe and @matzeni and explain your goals. We should avoid having clashes across different files, so if your line is defined in a module where other lines live, please coordinate among the contributors to the file to avoid conflicts. Once you are given green light to do changes, please do so and include in the description of this MR a little summary indicating the file(s) that you have modified as well as the changes to the lines.

Do not rebase or force-push to this branch without the consent of @mramospe and/or @matzeni, since this might lead to losses on the changes

Please follow the same format as in !3157 (merged).
