Filebeat using deprecated AgentCheck.increment and .decrement functions

[shcallaway]

Output of the info page

$ k exec -ti datadog-agent-snsfn bash
root@datadog-agent-snsfn:/# s6-svstat /var/run/s6/services/agent/
up (pid 349) 143 seconds

Additional environment details (Operating System, Cloud provider, etc):

AWS EKS

Steps to reproduce the issue:

1. Install the Filebeat check in Datadog agent pod in Kubenretes
2. Register Filebeat check by adding Datadog autodiscovery annotations to Filebeat pod
3. Stream logs of Datadog agent pod

Describe the results you received:

Filebeat integration prints the following deprecation notice:

datadog-agent 2020-03-24 19:43:53 UTC | CORE | WARN | (pkg/collector/python/datadog_agent.go:118 in LogMessage) | filebeat:e00f8fb4ebe0e9e6 | (base.py:536) | DEPRECATION NOTICE: `AgentCheck.increment`/`AgentCheck.decrement` are deprecated, please use `AgentCheck.gauge` or `AgentCheck.count` instead, with a different metric name

Describe the results you expected:

The Filebeat integration should be migrated to use the newer gauge and count functions, as there may be issues with continued use of increment and decrement.

Hallo @shcallaway, integrations in this repo are community maintained. I can ping @wk8 as filebeat codeowner about this but code contributions are welcome too.
