[BE] Support searching for similar traces

[Corgam]

New end-point: Input: trace ID Function: filter all similar traces:

• siblings from the same parent
• geo-location overlap of >=80% (required)
• >=50% tags the same
• >=50% datapoints the same Output: list of similar traces

@Corgam how would someone define a geo-location overlap of 2 points?

[Fr3574]

@Corgam same for tags, when would we say tags are the same? Do just one single tag has to be in both traces or is 100% overlap here only meant if all tags are the same?

After a meeting with UDK, we have decided it is no longer necessary.
