Detailed Description

This class parses the separated SelectorOptions defined in cvd_server.proto.

Note that the parsing is from the perspective of syntax.

In other words, this does not check the following, for example:

1. If the numeric instance id is duplicated
2. If the group name is already taken

Extends the common selector options with start specific ones.

The following are considered, and left empty if can't be figured out.

–base_instance_num, –instance_nums, –num_instances, instance_names_.size(), CUTTLEFISH_INSTANCE, and vsoc-suffix if it is the user name.

instance_names_.size() is effectively another –num_instances. CUTTLEFISH_INSTANCE and the suffix in order are considered as –base_instance_num if –base_instance_num is not given and –instance_nums is not given.
