Merge ElasticSearch tests to speed up full runs

[ryanohnemus]

There are currently 2 es tests: basic and compress.

For compress it had an entirely separate elasticsearch-compress and fluentbit-compress yaml files.

Differences are as follows:

Compression:
The elasticsearch file is only different than the basic one because it specified http.compression=true. According to the documentation, that is already the default when you do not use https, which we do not.

From the doc

http.compression
(Static, boolean) Support for compression when possible (with Accept-Encoding). If HTTPS is enabled, defaults to false. Otherwise, defaults to true.
Disabling compression for HTTPS mitigates potential security risks, such as a BREACH attack. To compress HTTPS traffic, you must explicitly set http.compression to true.

Therefore while the config looks different it's not actually different, so there's no need for a second elasticsearch config artifact.

elasticsearch-compress.yaml was removed.

Fluentbit:
The only differences between these tests were the es output in fluentbit-compress.yaml config had the compress gzip enabled. To cut out setup/teardown times. I removed the fluentbit-compress.yaml and added a second es OUTPUT in the fluentbit-basic.yaml that has compress gzip enabled. This now writes to a 2nd index in es called fluentbit-compress.

The basic intent here is to have a single fluentbit deployment that can attempt test sending with and without compression via 2 different outputs.

fluentbit-compress.yaml was removed.

The tests:
The only differences from the tests themselves is that the compressed version added a --compressed flag to the curl to request a compressed response.

compress.bats was removed. I merged the compressed test down into the basic.bats. The fluentbit and es deployment's happen in the setup_file function. Then 2 tests run quickly in sequence cutting a minute out of full runs.
