…pensearch-project#276) Sets the default value of space type to L2 in KNNIndexShard. KNNIndexShard is used during warmup to load segments into memory. For indices created in ES 7.1 and 7.4, they will not have this value set because the only space we supported was l2. So, we need to hardcode the defaults here. For nmslib, the ef_search parameter is configurable at load time. So, it needs to be passed as a parameter in both the search load phase as well as warmup. This commit adds it to the warmup phase and abstracts load parameters to a helper function so that it can be consistent for both search and warmup.

Jackson fix here: opensearch-project/OpenSearch#1982. Doesnt look to be backported. Junit seems to be fixed here: opensearch-project/OpenSearch#1888. Should be backported to 1.2. Not sure why 1.2 isnt picking this up here. |

Description
Sets the default value of space type to L2 in KNNIndexShard.
KNNIndexShard is used during warmup to load segments into memory. For
indices created in ES 7.1 and 7.4, they will not have this value set
because the only space we supported was l2. So, we need to hardcode the
defaults here.
For nmslib, the ef_search parameter is configurable at load time. So, it
needs to be passed as a parameter in both the search load phase as well
as warmup. This commit adds it to the warmup phase and abstracts load
parameters to a helper function so that it can be consistent for both
search and warmup.
