Bug 1961391

Description of problem:
We looked through some of the files we received back from translation and noticed some errors in the strings:
* There's a string for "and." The translators didn't have context for how it's used and some chose not to translate it. It would be better to provide that context for them.
* What is a BackingStore ? - should not have a space before the question mark
* "Pool management tasks are not supported for default pool and Openshift Container Storage's  external mode." - has an extra space before "external" and "Openshift" should be "OpenShift"
* "Data will be stored as is(no dedupe, compression, encryption) on the namespace stores. Namespace buckets allow for connecting to existing data and serving from them. Best used for existing data or when other applications (and native cloud services) need to access the data from outside the OpenShift Container Storage." - There should be a space before the parenthesis
* "Caching is a policy that creates local copies of the data. It saves the copies locally to improve performance for frequently accessed data. Each cached copy has a TTL and is verified against the hub. Each non-read operation(upload, overwrite, delete) is performed on the hub" - There should be a space before the parenthesis
* "A single namespace-store, defines the read and write target of the namespace bucket" - Shouldn't the comma be a semicolon? It seems like two sentences.
* "Select list of namespace stores, defines the read targets of the namespace bucket" - Shouldn't the comma be a semicolon? It seems like two sentences
* "Select a single namespace store, defines the write target of the namespace bucket" - Shouldn't the comma be a semicolon? It seems like two sentences
* "Select one namespace-store, defines the read and write targets of the namespace bucket" - Shouldn't the comma be a semicolon? It seems like two sentences
* "The number of buckets managed on Multicloud Object Gateway, Object bucket claims and the object bucket created as a result of object bucket claims on both Multicloud Object Gateway and RGW (if deployed)." - Seems like it should be two sentences and have a period instead of a comma.
