Hesperides-cli

Fixed
- made `--ignore-ssl-warnings` flag of `set_conf` command optionnal in non-interactive mode

- `get-properties --export`: for usage as environment variables in a shell

Fixed
- wrong files final location in `write-files`

Fixed

Fixed
- `write-files` when module selection options are provided

Changed
- `get-files` & `write-files` now accept a `--working-copy/--release` switch argument
- `write-files` now allow any number of selectors: `--path` / `--module-name` / `--module-version` / `--working-copy` / `--release` / `--instance-name`

Fixed
- `get-files` command, which was very buggy
- `perform-search-application-platforms` command, whose query params were incorrect

Added
- `write-files` command.
Usage example: `hesperides write-files --app KTN --ptf TEST --path 'VSLWAS' --module-name demoKatana-war --module-version 1.0.0.1 --working-copy`
- `--verbose` optional global parameter
- displaying warnings in case HTTP calls are made to deprecated endpoints
