Release v1.8.0

[fujimotos]

This ticket tracks the release of a new version of fluent-logger-golang.

• I'm planning to make a new release as v1.8.0.
• Mostly because Do not allow writing events after fluent.Close() #105 changed the behaviour of Close() (so not fully compatible with v1.7.0).

Release steps

• Add documentation for FluentNewtork=tls
• Add documentation for TlsInsecureSkipVerify={true,false}
• Document the new API behavior introduced by Do not allow writing events after fluent.Close() #105
• Add the release information to CHANGELOG.md
• Add the v1.8.0 tag to the master HEAD.
• Push the tag to fluent-logger-golang

I'm planning to make a release next week (probably Wednesday).

@tagomoris Do the release steps (posted above) look good to you?
This is my first release of a go module, so I want to do it safe..
