Implement a standard CLI command builder

[ahsimb]

The python-extension-common should provide a means to build a CLI command based on a standard set of parameters.

An extension's CLI command typically does some kind of deployment onto the database and/or bucket-fs. Therefore, a standard set of parameters should include the parameters required for creating a pyexasol connection and a bucket-fs path-like object, at both on-prem and SaaS databases.

The API shall include a function that will create a named command with all, a subset, or a superset of the standard parameters.

The user shall be able to configure a custom behavior for the standard or added parameters, as it is already implemented with the _ParameterFormatters class.

To build a CLI command, the user shall provide a custom or a standard callback function. An example of a standard function is the one that creates and runs the LanguageContainerDeployer using the provided CLI parameters. The standard command can be customized in terms of the number and behavior of the input parameters. For example, an extension can make a command using a fixed language alias instead of asking the user to enter it in the CLI.

The user can also combine two or more logically separate commands into one CLI command. For example, having a single installation command that deploys both the language container and the UDF scripts should improve user experience.
