Migrate remaining parsers to new structure introduced in #8791

[sspaink]

This pull request introduced an improved way to register parsers: #8791

We need to migrate all parsers to use this new structure so we can get rid of the old compatibility code.

• collectd: Migrate collectd parser to new structure #11353
• dropwizard
• from_urlencoded
• graphite
• grok
• influx
• influx_upstream
• logfmt
• nagios
• prometheus
• prometheusremotewrite
• value
• wavefront

@sspaink I think we said we were going to open a new bug for each parse in the team call this week? Should those replace this issue? Thanks!
