Deactiveted ADIOS1 Attribute test
Solved clang-format format and camelCase issues

* Support PutDeferred() in ADIOS1 writer

* added PerformPuts() to ADIOS1Writer

* refactor toolkit/interop/adios1/ADIOS1Common in preparation for having separate Write and Read classes

* Working towards ADIOS1 Reader. Changes the Engine.BeginStep() signature for all engines.

Passed ctest (MPI and nonMPI) excluding ADIOS1 engine, and Python bindings
HDF5, C bindings and C++ tests working
Introduced BeginStep EndStep functions
Renamed IO GetVariable/Attribute to InquireVariable/Attribute

Implemented basic buffer reading functionality
Added threading for bp serialization/deserialization
Refactored MPI functionality
Engine is now a reference
Initial Read API

* fix more example code

* make Open explicit in ADIOS1 toolkit. Fix handling open mode

* fix OpenModeToString() to serve adios 1 API's needs as well

* fix more example code

* make Open explicit in ADIOS1 toolkit. Fix handling open mode

1 Now IO (replaced Method) and is the factory for Variables and Engines
2 Reduced core components to user-public objects only
3 Moved and reorganized all helper functions to helper directory
4 Engines are now lightweight (except for ADIOS1Reader WIP) using MACRO
5 HF5Common and ADIOS1Common (except for Readers WIP) are now part of the toolkit so they can be reused by Engines
6 TransportMan is a new layer for transport management (file is default)
7 DataMan will be implemented under toolkit/transportman/dataman
8 Template separation (tcc and inl) applied all over the code
9 Improved Doxygen documentation

Runtime Issues:
DataMan library compilation (cacheman)
ADIOS1 Warning
TestADIOSInterfaceWrite catches exceptions

Some code for joined array reading in adios1 engine, incomplete. Rather should support it in adios1 itself.
Committed only to have a working Write/Read API so that we can have examples with global arrays finalized.

- Added examples/groupless/multistep writer example to the build
- Added ADIOS1 reader but it does not work yet
- Added heat transfer example reader
