Introduce matrix for unit tests.

reduce test matrix

remove mongoid-head gemfile as it is no longer used

reduce matrix entry to multi dimension matrix

test include for mongoid 9

exclude incompatible versions

remove compatible configurations

remove minor version specification to reduce number of combinations

reduce the number of parallel jobs and incorporate caching

remove caching

add caching

create single entry

add matrix with single entry

add ruby 3.0 and mongoid 8

complete string

add exclusion rules

add more exclusion rules

correct gem file name and add more exclusion rules

add more exclusion rules for mongoid_3

add exlcusion rules

add ruby 2.7 and mongoid 4

add more exclusion rules for ruby 3.7

get rid of mongodb 3.6

add ruby 2.7 and mongoid 3 and 4 to exlcusion list

add ruby 2.7 and mongoid 5

exclude ruby 2.6 and mongoid 3 and allow ruby 2.6 and mongoid 7 to run
