Related with this issue:
https://github.com/microsoft/mscclpp/issues/242. The user may use more
threads than the number specified in `fifo_size` to interact with the
FIFO. In this case, there will be unexpected behavior.
Update the interface to let user change fifo size on their demands.

828be48b21 Add Context and Endpoint classes to enable non-Communicator use-cases (#166) 
This PR implements and closes #137. The new `Endpoint` and `Context`
classes expose the connection establishing functionality from
`Communicator`, which now is only responsible for tying together the
bootstrapper with a context.

The largest breaking change here is that
`Communicator.connectOnSetup(...)` now returns the `Connection` wrapped
inside a `NonblockingFuture`. This is because with the way `Context` is
implemented a `Connection` is now fully initialized on construction.

Some smaller breaking API changes from this change are that
`RegisteredMemory` no longer has a `rank()` function (as there maybe no
concept of rank), and similarly `Connection` has no `remoteRank()` and
`tag()` functions. The latter are replaced by `remoteRankOf` and `tagOf`
functions in `Communicator`.

A new `EndpointConfig` class is introduced to avoid duplication of the
IB configuration parameters in the APIs of `Context` and `Communicator`.
The usual usage pattern of just passing in a `Transport` still works due
to an implicit conversion into `EndpointConfig`.

Miscellaneous changes:
-Cleans up how the PIMPL pattern is applied by making both the `Impl`
struct and the `pimpl_` pointers private for all relevant classes in the
core API.
-Enables ctest to be run from the build root directory.
