Added the dimension parameter to the following field types:
keyword
ip
Numeric field types (integer, long, byte, short)
The dimension parameter is of type boolean (default: false) and is used
to mark that a field is a time series dimension field.

This PR adds the following constraints to dimension fields:
It must be an indexed field and must has doc values
It cannot be multi-valued
The number of dimension fields in the index mapping must not be more than 16. This should be configurable through an index property (index.mapping.dimension_fields.limit)
keyword fields cannot be more than 1024 bytes long
keyword fields must not use a normalizer
Based on the code added in PR elastic#74450
Relates to elastic#74660
Adds a test for setting the maximum number of dimensions setting and tests the names and types of the metadata fields in the index. Previously we just asserted the count of metadata fields. That made it hard to read failures.
Test was failing because it was testing 1024 bytes long keyword and assertion was failing. Closes elastic#75225
This PR adds the time_series_metric parameter to the following field types:
Numeric field types
histogram
aggregate_metric_double
