Allow default values for options and parameters to be externalized

[remkop]

Picocli provides a PropertiesDefaultProvider implementation that hopefully fulfills our needs.

Users can create a .ami.properties file in their home directory, and define default values for ami options as well as options of ami subcommands in this file, as follows:

# this is an example ~/.ami.properties file

# for options, the key is the longest option name
cproject = /my/ami/project/123

# For subcommands, prefix with the subcommand name.
ami.assert.directoryname=/my/ami/project/123/assertable/dir

# for positional parameters, the key is the positional parameter’s param label.
ami.clean.<files>=/my/files/to/clean/by/default

Note that amidict is a separate top-level command and would need a separate ~/.amidict.properties file.

The top-level commands ami and amidict now support this functionality.

Reopening: I should add some documentation for this to the ami project README.

Many thanks!

we'll ask the group to try this out.
