Merge pull request #167 from pyansys/merge/0.4.0

Make ansys-dpf-core compatible with Ansys release 2022R1
Update master version to 0.4.dev0

> Enhancements:
> - native remote workflows capability: [Workflows](https://dpfdocs.pyansys.com/api/ansys.dpf.core.workflow.html) and [Operators](https://dpfdocs.pyansys.com/api/ansys.dpf.core.dpf_operator.html) instantiated on different servers can be connected together transparently to create distributed pre and post processing workflows. Workflows created on a given server can be moved to other servers.
> - add optional progress bar when [Operators](https://dpfdocs.pyansys.com/api/ansys.dpf.core.dpf_operator.html) or [Workflows](https://dpfdocs.pyansys.com/api/ansys.dpf.core.workflow.html) are evaluated. This uses the new Session API through grpc
> - server on Docker Container is started automatically with, either the environment variable DPF_DOCKER or either the parameter `docker_name` of the function [`start_local_server`](https://dpfdocs.pyansys.com/api/ansys.dpf.core.server.html) set to the name of the docker. Unit tests can be run on Docker Container
> - implement Integral Collection to connect and get output data as int, double or string arrays more efficiently from [Operators](https://dpfdocs.pyansys.com/api/ansys.dpf.core.dpf_operator.html) and [Workflows](https://dpfdocs.pyansys.com/api/ansys.dpf.core.workflow.html)
> - create generic calls to get and set field properties from and to the [MeshedRegion](https://dpfdocs.pyansys.com/api/ansys.dpf.core.meshed_region.html)
> - identify DPF entities in grpc databases by their entity IDs and their DataBase IDs to allow for better communication between servers
> - add capability to generate [operators](https://dpfdocs.pyansys.com/api/ansys.dpf.core.operators.html) python code client side
> - by default, the mesh is read when a displacement is requested (can be disabled with [`model.mesh_by_default = False`](https://dpfdocs.pyansys.com/api/ansys.dpf.core.model.html) )
> - new operators to support [averaging](https://dpfdocs.pyansys.com/api/ansys.dpf.core.operators.averaging.html) from elemental centroids results
> - improve handling of MAPDL coupled analysis 
> - create [path_utilities](https://dpfdocs.pyansys.com/api/ansys.dpf.core.operators.path_utilities.html) to offer helpers on path depending on the server os

> Bug fixes:
> - automatic code generation for [`model.results....`](https://dpfdocs.pyansys.com/api/ansys.dpf.core.results.html) is working for results with scripting names having " ", "/", "\", ".", ":", ";", ",", "(", ")" characters.
> - decorator `server_meet_version` "wraps" the method so that the call stack when exception are raised is correct
> - fetch named selections from the [MeshedRegion](https://dpfdocs.pyansys.com/api/ansys.dpf.core.meshed_region.html) only when it's specifically required to improve performances
> - properly release memory server side when time/frequencies are requested by the [TimeFreqSupport](https://dpfdocs.pyansys.com/api/ansys.dpf.core.time_freq_support.html)
> - add more unary calls in [ResultInfo](https://dpfdocs.pyansys.com/api/ansys.dpf.core.result_info.html) service

> Documentation fixes:
> - README.md reference pydpf-core instead of DPF-Core
> - improve spelling
