feat (jans-config-api) : allow multiple pattern search in apis

[duttarnab]

Is your feature request related to a problem? Please describe.

In config-api APIs, we have a pattern query parameter allowing a single pattern search. We need multiple pattern search feature in APIs.

For example https://admin-ui-test.gluu.org/jans-config-api/api/v1/attributes?pattern=birthDate|jansAdminUIRole|c

Reopening this issue.

• For attributes API the multiple pattern search works for only displayName. It will be useful for clients like admin-ui, tui if it works for inum.

• We need to implement multiple pattern searches for all apis. (Need this in scopes apis to fix fix(admin-ui): hindrance on client scope assignment GluuFederation/flex#502)
