refactor(coordinator): and gsctl to support FLEX interactive (#3297)

* Remove the `show_log` and `log_level` attributes from the`SessionConfig` class, 
and add them to the global `Config` class along with a new `solution` attribute, 
which indicates the solution type under the FLEX architecture
* Add a new file `./python/graphscope/gsctl/commands/common_command.py`,
which defines a group of commands that are common to all solutions under
the FLEX architecture, such as `connect` and `close`
* Add a new file `./python/graphscope/gsctl/commands/dev_command.py`,
which defines a group of commands for GraphScope development, such as
`install-deps`, `make`, `make-image`, and `test`
* Modify the `./python/graphscope/gsctl/gsctl.py` file, which is the
main script of the `gsctl` utility, to use the `get_command_collection`
and `get_current_context`
* Update the documentation of the `gsctl` command-line utility in the
`./docs/utilities/gs.md` file, to reflect the new features and modes of
operation under the FLEX architecture
