Directory support

This MR adds two features:

- Creation of directories on the output. As cargo is normally running in the prolog the user has zero capabilities to create directories on the adhoc filesystem (as it is ephemeral). This MR creates the needed directories.

- If the input contains a directory, we get all the files recursively. Before this MR only files can be used as input. The behaviour is that the input is used as prefix, i.e., relative directory, and will be put inside the output.

- Prepares for 0.3.0 release

See merge request !14

Directories `CMAKE_INSTALL_BINDIR` and `CMAKE_INSTALL_DATADIR` are now
exported as package variables `CARGO_BIN_INSTALL_DIR` and
`CARGO_DATA_INSTALL_DIR`. This allows consuming projects to retrieve
these values by using `find_package(cargo)`.

Resolve "Add a CLI tool for requesting data transfers."

This MR adds the `ccp` tool to Cargo so that data transfers can be started
from the command line. The tool supports the following arguments:

```console
$ ccp -h
Cargo parallel copy tool
Usage: ccp [OPTIONS]

Options:
  -h,--help                   Print this help message and exit
  -s,--server ADDRESS         Address of the Cargo server (can also be
                              provided via the CCP_SERVER environment
                              variable).
  -i,--input SRC...           Input dataset(s)
  -o,--output DST...          Output dataset(s)
  --if FLAGS                  Flags for input datasets. Accepted values
                                - posix: read data using POSIX (default)
                                - mpio: read data using MPI-IO
  --of FLAGS                  Flags for output datasets. Accepted values
                                - posix: write data using POSIX (default)
                                - mpio: write data using MPI-IO
```                                

Once a Cargo server is up and running, `ccp` can be used as follows:

```console
$ srun -N4 cargo -l ofi+tcp://192.18.0.10:62000 -o cargo.log
[...]
$ ccp -s ofi+tcp://192.18.0.10:62000 -i input0.dat input1.dat -o output0.dat output1.dat
```

Modes of operation that control how transfers should be executed can be selected
through the the `--if` and `--of` options. For now, `posix` and `mpio` modes are
supported. Note however that not all combinations are supported yet, and that 
performance will depend on whether the underlying file system supports parallel
I/O through MPI-IO.
