AthenaServices + AthenaPoolExampleAlgorithms: Prepare ThinningCache for setting lossy float compression information

This MR builds on !35326 (merged). It extends Scott's recent updates on thinning (to accommodate per-stream variable selection in AthenaMT) to use the same infrastructure for setting/getting the lossy float compression information.

The main idea here is to store the lossy float compression information (which is essentially a map that holds a set of AuxIDs that should be compressed for each compression level) into the ThinningCache as opposed to the EDM objects themselves. When fully implemented, AthenaOutputStream is going to store the SG::CompressionInfo into the event store. ThinningCacheTool inserts this into a ThinningCache and one can query the cache via ThinningInfo. The latter is actually passed onto SG::copyAuxStoreThinned where the thinning/selection/compression is applied.

This MR puts everything into place for filling the ThinningCache for the lossy float compression information. However, it's not yet used (i.e. the last bit above), which will be implemented in an upcoming MR. Also, once we switch to this new method, we won't need the IAuxStoreCompression that is implemented in AuxContainerBase anymore. So, that bit will also be cleaned up.

This MR is self-consistent and it's already fairly hefty. So, in order to ease the review, I'm submitting this now and will complete the development in a future MR, which will also include the clean-up (but I might also break that bit down too).

mentioned in merge request !35326 (merged)

I'll take a closer look at the unit test results on Monday, but from a quick scan, I see almost all of the failures are the same as the recent nightlies. There are new ones, e.g. CaloRec_CaloThinCellsByClusterAlg_test_ctest, but I have a hunch that at least some of these might be related to !35389 (merged) which got merged earlier today since the pattern looks suspiciously related:

-Py:PropertyProxy  WARNING Found 2 duplicates among the 1069 genConfDb files :
-Py:PropertyProxy  WARNING --------------------------------------------------
-Py:PropertyProxy  WARNING   -<component name>: <module> - [ <duplicates> ]
-Py:PropertyProxy  WARNING --------------------------------------------------
-Py:PropertyProxy  WARNING   -BSFilter: OverlayByteStreamAlgs.OverlayByteStreamAlgsConf - ['OverlayByteStreamUtils.OverlayByteStreamUtilsConf', 'OverlayByteStreamUtils.OverlayByteStreamUtilsConf']

-Py:PropertyProxy  WARNING Fix your cmt/requirements file !!

So let me tag @tadej as these will probably fail in today's nightly, too.

This should be just an incremental build failure. Once a full build is done it should go away.

Looks ok. thanks.

OK, comparing against the unit tests of 2020-08-06T2137 the additional failures are all about the overlay issue I mentioned above as far as I can see. Tadej says this is due to incremental build. Therefore, we should be OK w/ this MR.

Moving forward with L1 approval.

added review-approved label and removed review-pending-level-1 label

Given this MR is not marked as urgent, I'd rather give CI yet another try and, if it does not add new failures to what is already present in 2020-08-09T2137, then I will go ahead and merge it.

Jenkins please retry a build

I see one unit test which failed for this MR and did not fail in 2020-08-09T2137: this is SCT_Digitization_SCT_DigitizationMT_test_ctest.

@amete and @tadej , any comments?
