6d00b39886 cleanup: move log functions to new internal/util/log package
Moving the log functions into its own internal/util/log package makes it
possible to split out the humongous internal/util packages in further
smaller pieces. This reduces the inter-dependencies between utility
functions and components, preventing circular dependencies which are not
allowed in Go.

43f753760b cleanup: resolve nlreturn linter issues
nlreturn linter requires a new line before return
and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

095a82f37d util: returns actual error instead of ErrPoolNotFound
This commit returns actual error returned by the go-ceph API
to the function GetPoolName(..) instead of just returning
ErrPoolNotFound everytime there is error getting the pool id.
There is a issue reported in which the snapshot creation
takes much more time to reach True state
(i.e., between 2-7 mins) and keeps trying to create with
below error though pool is present:
rpc error: code = NotFound desc = pool not found: pool ID (21)
not found in Ceph cluster.

Since we cannot interpret the actual error for the delay in
snapshot creation, it is required to return the actual error
as well so that we can uderstand the reason.

36469b87e2 util: make ExecComand return stdout and stderr as string
Most consumers of util.ExecCommand() need to convert the returned []byte
format of stdout and/or stderr to string. By having util.ExecCommand()
return strings instead, the code gets a little simpler.

A few commands return JSON that needs to be parsed. These commands will
be replaced by go-ceph implementations later on. For now, convert the
strings back to []byte when needed.

ddac66d76b util: use context.Context for logging in ExecCommand
All calls to util.ExecCommand() now pass the context.Context. In some
cases this is not possible or needed, and util.ExecCommand() will not
log the command.

This should make debugging easier when command executions fail.

8393fbe40b util: simplify error handling
The sentinel error code had additional fields in the errors, that are
used nowhere.  This leads to unneccesarily complicated code.  This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.
