Integration tests to validate data going to OpenSearch

[dlvenable]

Is your feature request related to a problem? Please describe.

We were recently concerned that Data Prepper was sending invalid data to OpenSearch. It turns out we don't have test cases to verify many different data combinations are correctly sent to OpenSearch.

Describe the solution you'd like

Create new tests in the OpenSearch integration tests (OpenSearchIT) to test various data combinations.

Examples:

long

• largest long value
• smallest long value
• other extreme values
• 1234567891011121314 (this was the value that originally initiated this; see [BUG] Large values do not display correctly in OpenSearch Dashboards OpenSearch-Dashboards#5485)
• null

int

• largest int value
• smallest int value
• other extreme values
• null

boolean

• true
• false
• null

string

• Very large strings
• Strings with special characters
• Strings with alternate character sets (e.g. non-Latin languages)

double

• large double values
• smallest double values (fractional of 0)
• both positive and negative
• other extreme values
• null

float

• large double values
• smallest double values (fractional of 0)
• both positive and negative
• other extreme values
• null

Any other values that may possibly have issues being serialized or sent to OpenSearch.
