chore: log pretty print cache config on instantiation

[malandis]

Logs a pretty printed version of the cache configuration in the cache
client factory function.

When printing the cache configuration before, we would see something like this:

 &{loggerFactory:0x1400000ee80 transportStrategy:0x1400000ca50 retryStrategy:{eligibilityStrategy:{} maxAttempts:3 log:0x1400000ca68} numGrpcChannels:1 readConcern:balanced}

This contains pointers to parts of the configuration that should be dereferenced and recursively represented. We override the String function on the appropriate structs to get this. Now we will see:

Configuration{loggerFactory=DefaultMomentoLoggerFactory{level=20}, transportStrategy=TransportStrategy{grpcConfig=GrpcConfiguration{deadline=5s, keepAlivePermitWithoutCalls=true, keepAliveTimeout=1s, keepAliveTime=5s, maxSendMessageLength=5243000, maxReceiveMessageLength=5243000}, maxIdle=0s}, retryStrategy=fixedCountRetryStrategy{eligibilityStrategy={}, maxAttempts=3, log=DefaultMomentoLogger{loggerName=fixed-count-retry-strategy, level=20}}, numGrpcChannels=1, readConcern=balanced}

We further log the properties from the cache client constructors to log all relevant settings. We provide a String function for CredentialProvider where we censor the auth token. Here is what the log statement looks like:

[2025-01-17T00:50:18Z] INFO (CacheClient): Creating cache client with settings: CacheClientProps{CacheName: , Configuration: Configuration{loggerFactory=DefaultMomentoLoggerFactory{level=20}, transportStrategy=TransportStrategy{grpcConfig=GrpcConfiguration{deadline=5s, keepAlivePermitWithoutCalls=true, keepAliveTimeout=1s, keepAliveTime=5s, maxSendMessageLength=5243000, maxReceiveMessageLength=5243000}, maxIdle=0s}, retryStrategy=fixedCountRetryStrategy{eligibilityStrategy={}, maxAttempts=3, log=DefaultMomentoLogger{loggerName=fixed-count-retry-strategy, level=20}}, numGrpcChannels=1, readConcern=balanced}, CredentialProvider: CredentialProvider{authToken=ey***uM, controlEndpoint=Endpoint{Endpoint=control.cell-4-us-west-2-1.prod.a.momentohq.com:443, InsecureConnection=false}, cacheEndpoint=Endpoint{Endpoint=cache.cell-4-us-west-2-1.prod.a.momentohq.com:443, InsecureConnection=false}, tokenEndpoint=Endpoint{Endpoint=token.cell-4-us-west-2-1.prod.a.momentohq.com:443, InsecureConnection=false}, storageEndpoint=Endpoint{Endpoint=storage.cell-4-us-west-2-1.prod.a.momentohq.com:443, InsecureConnection=false}}, DefaultTtl: 1m0s, EagerConnectTimeout: 30s}

I considered adding a String method to relevant configuration interface types. Since that would be a breaking change for existing users that have made their own implementation, I have foregone that.

thanks for the fast turnaround!
