Common: api_request_enrichment_config schema version 1-0-1 support

[lmath]

See: #669

check 1 - api request enrichment with schema version 1-0-0 works on a pipeline

this change is in 3.2.4-rc2

1. I brought up a GCP pipeline and ensured enrichment version was set to 3.2.4-rc2
2. I set up a minimal api_request_enrichment_config.json which configures an api, one input and one output which is valid for schema version 1-0-0 (has a non-zero value for cache size)
3. I added a schema to the dev sandbox iglu server to configure the output in api_request_enrichment_config.json
4. I added a subscription to the good event topic so that I'd be able to pull and look at good events
5. I sent a test event to the collector of my GCP pipeline
6. I was able to see the good event coming through, enriched with the output field I had defined in api_request_enrichment_config.json and matching the schema I added to the iglu server.

check 2 - api request enrichment with schema version 1-0-1 works on a pipeline

same as above, except for 2:
I set up a minimal api_request_enrichment_config.json which configures an api, one input and one output which is valid for schema version 1-0-1 (where cache size is 0) and then re-ran terraform apply

I wondered initially if the criteria should be valid == 1-0-0 or 1-0-1 rather than valid == 1-0-x

but it seems like ApiRequestEnrichment was the outlier here. See: WeatherEnrichement, YauaaEnrichement, HttpHeaderExtractorEnrichment

Loved the added history and reasoning.👍🏻
