NR-181605 Add sendMetrics param to newrelic output plugin in FB conf file

[Sivakumar3695]

Issue link: NR-181605

Description

• For log forwarding, a new param - sendMetrics is introduced in the newrelic-fluent-bit-output plugin.
• While constructing the FluentBit config file, the output plugin should contain sendMetrics param if verbose logging is enabled for supervisor via log_filter in the newrelic-infra.yml file.

Changes

• the new param is introduced in the template file
• from config/config.go LogForward, verbose logging mode is checked and set to this field - FluentBitVerbose
• The above FluentBitVerbose field is used to check if sendMetrics param should be in fluentBit config file.

Test cases

• Test cases for the new changes are added in cfg_test.go and loader_test.go
