Use PerThreadCache to create code-owners plugin config only once per request

Each call of CodeOwnersPluginConfiguration#getProjectConfig causes a
load of the plugin config with inheritance via
pluginConfigFactory#getProjectPluginConfigWithInheritance(projectName,
pluginName) which is not free. CodeOwnersPluginConfigSnapshot that is
returned by CodeOwnersPluginConfiguration#getProjectConfig caches the
plugin config, hence creating CodeOwnersPluginConfigSnapshot only once
and reading multiple config param from it is more efficient. Reduce the
number of CodeOwnersPluginConfiguration#getProjectConfig calls by
caching CodeOwnersPluginConfigSnapshort in the PerThreadCache so that
the code-owners plugin config is only created once per request.
