Allow to choose specific envs when calling dump_environments service

[alvarovillena]

Currently, dump_environments service unloads every map and environment.

• Add the option to specify a single environment to be dumped, along with the maps hanging from it.
• Dump every environment as we are doing now if we use an asterisk.
• It should fail if we don't indicate any environment.
