   ## What changes were proposed in this pull request?
   
   RANGER-5541 and RANGER-5812 added validation of endpoint URLs in service 
configurations for Test Connection and resource lookup. This PR applies that 
validation consistently for KMS services.
   
   ServiceMgr: validateOutboundServiceConfigs() now evaluates the endpoint the 
client actually connects to. Nested provider URIs (kms://...) are unnested the 
same way the KMS client does it (ProviderUtils.unnestUri). Encoded values are 
normalised before validation. Every host in a multi-host (HA) provider list is 
validated.
   
   KmsKeyMgr: the endpoint validation now runs in getKMSURL(), before Key 
Manager operations (get, search, create, rollover, delete) connect to the 
configured provider. A validation failure is reported to the caller as an 
invalid-input error instead of "service not found".
   
   KmsKeyMgr / KMSClient: HTTP redirects are no longer followed by the Key 
Manager and Test Connection KMS clients.
   
   Behaviour notes:
   
   A KMS provider that responds with a redirect (for example http to https) 
must now be configured with its final scheme and host.
   
   Provider endpoints that do not pass the existing service-config endpoint 
validation are now also rejected for Key Manager operations, not only for Test 
Connection.
   
   ## How was this patch tested?
   
   New TestKmsProviderHostCheck (security-admin): endpoint validation across 
validateConfig, lookupResource and all Key Manager operations; HA provider 
lists continue to be accepted; ordinary config values are unaffected; redirects 
are not followed.
   
   New TestKMSClientRedirect (plugin-kms): Test Connection client does not 
follow redirects.
   
   Updated TestKmsKeyMgr: the test provider URL fixture now uses a 
documentation address (192.0.2.10) so it passes the endpoint validation.
   
   Existing TestKmsKeyMgr, TestServiceMgr, KMSClientTest pass, including the HA 
failover tests.
   
   mvn clean install on security-admin and plugin-kms.
