deprecate config TRIMMED_DEFINITION_MONGO_COLLECTION_NAME

[elrayle]

NOTE: This is merging into prod branch to allow release of v1.1.0 as a minor release.. It will be backported to master branch.

---

Deprecated config: TRIMMED_DEFINITION_MONGO_COLLECTION_NAME Replacement config: DEFINITION_MONGO_TRIMMED_COLLECTION_NAME

Config TRIMMED_DEFINITION_MONGO_COLLECTION_NAME was removed in PR https://github.com/clearlydefined/service/pull/987. To avoid a major version change in the next release, the config is being added back in and deprecated.

New processing:

• if the old config has a value, a deprecation message is written to the console
• if the new config is specified, its value is used and the old one is ignored if it exists
• if only the old config is specified, its value is used
• otherwise, if neither are specified, the default is used

DO NOT MERGE The branch was created from master, so it can't be merged into prod.
