internal/gengapic: remove omit-snippets option

[quartzmo]

The omit-snippets generator option is no longer used and should be removed, including all related conditionals in internal/gengapic.

Hi @quartzmo
can I understand if there is any flag to remove snippets?
Thanks

[quartzmo]

@jjkoh95 I'm sorry, I don't understand exactly. What do you want to do?

Hi @quartzmo
I wish to generate clients without snippets, is it possible?
I'm not sure if this project is dedicated only to google apis, but I have some protobuf definition that i need to generate its equivalent http clients.

Yes, the omit-snippets flag is documented in the readme. If set to true (the default is false), snippets will not be generated. However, this flag may be removed in the future. If you indeed use it in production, please comment on this issue to let us know.

I believe this flag might have already been removed in the latest version, setting ommit-snippets to true still give me the snippets.

github.com/googleapis/gapic-generator-go v0.39.4

It is not too painful for me to remove it everytime i generate it, but it seems to be redundant given the example test file is generated altogether.

Unfortunately, I think you'll just need to keep removing the snippets. To comply with this issue, the motivation for which is to simplify the codebase, the omit-snippets flag will someday be removed anyway.
