The catalogue can receive polymorphic items as input for recording.
The strict sequencing of fSeqs is still enforced.
Currently, 2 items types are recorded: files and placehoders.
Files are recorded to the tape catalogue, while place holders are not,
but they are used to enforce the fSeq sequencing.

Done

Fixed.

RdbmsCatalogue::checkAndGetNextArchiveFileId() now calls getCachedRequesterMountPolicy() and getCachedRequesterGroupMountPolicy()

RdbmsCatalogue::getRequesterGroupMountPolicy() now returns optional<common::dataStructures::MountPolicy>

RdbmsCatalogue::getRequesterGroupMountPolicy() now returns std::unique_ptr<> instead of a raw pointer

Replaced calls to RdbmsCatalogue::getExpectedNbArchiveRoutes() with getCachedExpectedNbArchiveRoutes()

cta/CTA#212 Verify the tape catalogue enforces the rule that all tape copies have the same file size and checksum.

Fixed.

Catalogue classes now propagate exception::LostDatabaseConnection

Added CatalogueRetryWrapper.hpp

This reverts commit fc001693.

The CI was incorrectly failing.  There was nothing wrong with
the original commit that made the Catalogue class a pure
interface.

This reverts commit abe44e72.
