[Enhancement] Fetch system index mappings from json file instead of s…

…tring constants (opensearch-project#3153) * feat(index mappings): fetch mappings and version from json file instead of string constants Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactor: changing exception being thrown Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * chore: remove unused file Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * chore: fix typo in comment Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * chore: adding new line at the end of files Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * feat: add test cases Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * fix: remove test code Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * fix(test): in main the versions were not updated appropriately Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactor: move mapping templates under common module Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactor: ensure that conversationindexconstants reference mlindex enums rather than use their own mappings Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactor: update comment Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactor: rename dir from mappings to index-mappings Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * fix: add null checks Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * fix: adding dependencies for testing Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * fix(test): compare json object rather than strings to avoid eol character issue Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactor: combine if statements into single check Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * refactoring: null handling + clean code Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> * spotless apply Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com> --------- Signed-off-by: Pavan Yekbote <mail2pavanyekbote@gmail.com>
